🌗 Tailwind CSS Theme Variants

This Tailwind CSS plugin registers variants for theming beyond just light and dark modes without needing custom properties. It has support for

You are recommended to check out the comparison table of all Tailwind CSS theming plugins below before committing to any one. By the way, you might have noticed this plugin's documentation / README is very long—don't let that frighten you! I designed it to be overdocumented and as exhaustive as possible, and since most of it is long code snippets, it's shorter than it looks and you don't need to go through it all to do well!

⬇️ Installation

npm install --save-dev tailwindcss-theme-variants

🛠 Basic usage

Using selectors to choose the active theme

With this Tailwind configuration,

const { themeVariants } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        backgroundColor: {
            "gray-900": "#1A202C",
        },
    },

    plugins: [
        themeVariants({
            themes: {
                light: {
                    selector: ".light-theme",
                },
                dark: {
                    selector: ".dark-theme",
                },
            },
        }),
    ],
};

this CSS is generated:

.bg-gray-900 {
    background-color: #1A202C
}

/* If you're having trouble understanding,
   imagine it said html instead of :root,
   like in the example HTML below */

:root.light-theme .light\:bg-gray-900 {
    background-color: #1A202C
}

:root.dark-theme .dark\:bg-gray-900 {
    background-color: #1A202C
}

We can implement a simple themed button in HTML like this:

<html class="light-theme"> <!-- Change to dark-theme -->
    <button class="light:bg-teal-200   dark:bg-teal-800 
                   light:text-teal-700 dark:text-teal-100">
        
        Sign up
    </button>
</html>

This will result in dark blue text on a light blue background in the light theme, and light blue text on a dark blue background in the dark theme.

💡 You can choose more than just classes for your selectors. Other, good options include data attributes, like [data-padding=compact]. You can go as crazy as .class[data-theme=light]:dir(rtl), for example, but I think that's a bad idea!

Using media queries to choose the active theme

You may rather choose to tie your theme selection to matched media queries, like prefers-color-scheme:

const { themeVariants, prefersLight, prefersDark } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        backgroundColor: {
            "teal-500": "#38B2AC",
        },
    },

    plugins: [
        themeVariants({
            themes: {
                light: {
                    mediaQuery: prefersLight /* "@media (prefers-color-scheme: light)" */,
                },
                dark: {
                    mediaQuery: prefersDark /* "@media (prefers-color-scheme: dark)" */,
                },
            },
        }),
    ],
};

Which generates this CSS:

.bg-teal-500 {
    background-color: #38B2AC
}

@media (prefers-color-scheme: light) {
    .light\:bg-teal-500 {
        background-color: #38B2AC
    }
}

@media (prefers-color-scheme: dark) {
    .dark\:bg-teal-500 {
        background-color: #38B2AC
    }
}

⚙️ Full configuration

This plugin expects configuration of the form

{
    themes: {
        [name: string]: {
            // At least one is required
            selector?: string,
            mediaQuery?: string,
        },
    },

    baseSelector?: string,
    fallback?: boolean,
}

Where each parameter means:

Fallback

Media queries

With the same media-query-activated themes as above,

themes: {
    light: {
        mediaQuery: prefersLight /* "@media (prefers-color-scheme: light)" */,
    },
    dark: {
        mediaQuery: prefersDark /* "@media (prefers-color-scheme: dark)" */,
    },
},

we can create a table to show what the active theme will be under all possible conditions:

<table> <thead> <tr align="center"> <th align="left">Matching media query</th> <th>Neither</th> <th><code>prefers-color-scheme: light</code></th> <th><code>prefers-color-scheme: dark</code></th> </tr> </thead> <tbody> <tr align="center"> <th align="left">Active theme</th> <td>None</td> <td><code>light</code></td> <td><code>dark</code></td> </tr> </tbody> </table>

The whole point of the fallback feature is to address that None case. It could mean that the visitor is using a browser that doesn't support prefers-color-scheme, such as IE11. Instead of leaving them on an unthemed site, we can "push" them into a particular theme by specifying fallback.

themes: {
    light: {
        mediaQuery: prefersLight /* "@media (prefers-color-scheme: light)" */,
    },
    dark: {
        mediaQuery: prefersDark /* "@media (prefers-color-scheme: dark)" */,
    },
},
// New addition
fallback: true,
// Because `light` is the first theme in the list, that is what will be fallen back to

Which will change the generated CSS to activate light earlier than any media queries—since those are later in the file, they could still take precedent over this fallback case. You could think of light as the default theme in this case.

.bg-teal-500 {
    background-color: #38B2AC
}

/* Different! */
.light\:bg-teal-500 {
    background-color: #38B2AC
}

@media (prefers-color-scheme: dark) {
    .dark\:bg-teal-500 {
        background-color: #38B2AC
    }
}

Which, in turn, changes the active theme table to:

<table> <thead> <tr align="center"> <th align="left">Matching media query</th> <th>Neither</th> <th><code>prefers-color-scheme: light</code></th> <th><code>prefers-color-scheme: dark</code></th> </tr> </thead> <tbody> <tr align="center"> <th align="left">Active theme</th> <td><code>light</code></td> <td><code>light</code></td> <td><code>dark</code></td> </tr> </tbody> </table>

💡 Even though background-color has been used in every example so far, theme variants are available for any utility.

Selectors

fallback also works for selector-activated themes.

💡 If you control themes on your site by adding / removing classes or attributes on the html or body element with JavaScript, then visitors without JavaScript enabled would see the fallback theme!

themes: {
    dark: {
        selector: ".dark-theme",
    },
    light: {
        selector: ".light-theme",
    },
},
fallback: true, // Fall back to `dark`

Fallback always chooses the first theme in your list of themes. To choose a different theme, change the order of themes.

These options, with the same Tailwind config as before with backgroundColor: ["dark", "light"] (because that matches the order in themes) in variants, will generate:

.bg-gray-900 {
    background-color: #1A202C;
}

:root .dark\:bg-gray-900 {
    background-color: #1A202C;
}

:root.light-theme .light\:bg-gray-900 {
    background-color: #1A202C;
}

Which has the active theme table:

<table> <thead> <tr> <th align="left">Matching selector</th> <th align="left">Active theme</th> </tr> </thead> <tbody> <tr> <th align="left">Neither</th> <td align="center"><code>dark</code></td> </tr> <tr> <th align="left"><code>:root.light-theme</code></th> <td align="center"><code>light</code></td> </tr> <tr> <th align="left"><code>:root.dark-theme</code></th> <td align="center"><code>dark</code></td> </tr> </tbody> </table>

Stacked variants

You can "stack" built-in or custom variants on top of the existing theme variants. We call it stacking because multiple variants are required: like in night:focus:border-white, the border will only be white if the night theme is active and the element is :focused on.

Here's an example of combining prefers-contrast: high with the :hover variant:

const { themeVariants, prefersHighContrast } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        // Your Tailwind CSS theme configuration
    },
    plugins: [
        themeVariants({
            themes: {
                "high-contrast": {
                    mediaQuery: prefersHighContrast /* "@media (prefers-contrast: high)" */,
                },
            },
        }),
    ],
};

You could create a simple card that uses contrast pleasant for fully sighted visitors, or functional high contrast for those who specify it:

<div class="bg-gray-100   high-contrast:bg-white
            text-gray-800 high-contrast:text-black">
    
    <h1>Let me tell you all about...</h1>
    <h2>... this great idea I have!</h2>

    <a href="text-blue-500       high-contrast:text-blue-700
             hover:text-blue-600 high-contrast:hover:text-blue-900">

        See more
    </a>
</div>

Another—complex—example: suppose you want to zebra stripe your tables, matching the current theme, and change it on hover:

const { themeVariants } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        // Your Tailwind CSS theme configuration
    },

    plugins: [
        themeVariants({
            baseSelector: "table.themed",
            themes: {
                "no-accent": { selector: "" },
                "green-accent": { selector: ".themed-green" },
                "orange-accent": { selector: ".themed-orange" },
            },
        }),
    ],
};

We can then implement the themeable table in HTML (Svelte) like so:

<table class="themed themed-green"> <!-- Try changing themed-green to themed-orange or removing it -->
    {#each people as person}
        <tr class="no-accent:bg-white               green-accent:bg-green-50             orange-accent:bg-orange-50
                   no-accent:hover:bg-gray-100      green-accent:hover:bg-green-100      orange-accent:hover:bg-orange-100
                   no-accent:odd:bg-gray-100        green-accent:odd:bg-green-100        orange-accent:odd:bg-orange-100
                   no-accent:odd:hover:bg-gray-200  green-accent:odd:hover:bg-green-200  orange-accent:odd:hover:bg-orange-100
                  ">

            <td>{person.firstName} {person.lastName}</td>
            <td>{person.responsibility}</td>
            <!-- ... -->
        </tr>
    {/each}
</table>

Responsive variants

Responsive variants let you distinguish the current breakpoint per theme. For example, lg:green-theme:border-green-200 will have a green-200 border only when the breakpoint is lg (or larger) and green-theme is active.

const { themeVariants } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        // Your Tailwind CSS theme configuration
    },
    
    plugins: [
        themeVariants({
            themes: {
                day: { selector: "[data-time=day]" },
                night: { selector: "[data-time=night]" },
            },
        }),
    ],
};

With this, we could make the landing page's title line change color at different screen sizes "within" each theme:

<h1 class="day:text-black          night:text-white
           sm:day:text-orange-800  sm:night:text-yellow-100
           lg:day:text-orange-600  lg:night:text-yellow-300">
    
    The best thing that has ever happened. Ever.
</h1>

We could also make a group of themes for data density, like you can configure in GMail:

const { themeVariants } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        // Your Tailwind CSS theme configuration
    },

    plugins: [
        themeVariants({
            // baseSelector is ":root"
            themes: {
                comfortable: { selector: "[data-density=comfortable]" },
                compact: { selector: "[data-density=compact]" },
            },
            // Fall back to the first theme listed (comfortable) when density is not configured
            fallback: true,
        }),
    ],
};

This will allow us to configure the padding for each theme for each breakpoint, of a list of emails in the inbox (so original!):

<li class="comfortable:p-2     compact:p-0
           md:comfortable:p-4  md:compact:p-1
           xl:comfortable:p-6  xl:compact:p-2">
    
    FWD: FWD: The real truth behind...
</li>

Extra stacked variants

You can still stack extra variants even while using responsive variants, but this is not commonly needed.

Here's an example:

const { themeVariants, landscape, portrait } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        // Your Tailwind CSS theme configuration
    },

    plugins: [
        themeVariants({
            themes: {
                landscape: {
                    mediaQuery: landscape,
                },
                portrait: {
                    mediaQuery: portrait,
                },
            },
            fallback: true,
        }),
    ],
};

We can make an h1 change size based on orientation and breakpoint and hover for readability (this is definitely a contrived example):

<h1 class="landscape:text-base          portrait:text-xs
           sm:landscape:text-lg         sm:portrait:text-sm
           sm:landscape:hover:text-xl   sm:portrait:hover:text-md
           lg:landscape:text-2xl        lg:portrait:text-lg
           lg:landscape:hover:text-3xl  lg:portrait:hover:text-xl">
    
    This article title will try to change size so that it stays readable... hopefully.
</h1>

More realistically, you might just want to change a link color on hover depending on the breakpoint and theme.

Using both selectors and media queries

⚠️ If you use both selectors and media queries to activate themes, then make sure that each specified class is specified as an all or nothing approach. For instance, if you have winter and summer themes and want to add the winter:bg-teal-100 class, then you also need to add the summer:bg-orange-200 class. If you don't do this, then it will look like the values from an theme that's supposed to be inactive are "leaking" into the active theme.

Every feature previously discussed will still work as you'd expect, even when you decide to also add selectors or media queries to theme control. When both selectors and media queries are in use, selectors will always take priority over media queries. This allows the flexibility of defaulting to media queries and overriding with JavaScript!

For example, see this plugin call:

// Rest of the Tailwind CSS config and imports...
plugins: [
    themeVariants({
        themes: {
            cyan: {
                selector: ".day",
                mediaQuery: prefersLight,
            },
            navy: {
                selector: ".night",
                mediaQuery: prefersDark,
            },
        },
    }),
],

It has the corresponding active theme table:

<table> <thead> <tr> <th align="left">Match</th> <th align="left">Neither</th> <th align="left"><code>prefers-color-scheme: light</code></th> <th align="left"><code>prefers-color-scheme: dark</code></th> </tr> </thead> <tbody> <tr> <th align="left">Neither</th> <td align="center">None</td> <td align="center"><code>cyan</code></td> <td align="center"><code>navy</code></td> </tr> <tr> <th align="left"><code>:root.day</code></th> <td align="center"><code>cyan</code></td> <td align="center"><code>cyan</code></td> <td align="center"><code>cyan</code></td> </tr> <tr> <th align="left"><code>:root.night</code></th> <td align="center"><code>navy</code></td> <td align="center"><code>navy</code></td> <td align="center"><code>navy</code></td> </tr> </tbody> </table>

As previously noted, when a required selector is present, it takes precendence over the media queries. Stated another way, the media queries only matter when no selector matches.

⚠️ If you are stacking variants on while using both selectors and media queries to activate themes, then make sure that each stacked variant is specified as an all or nothing approach on each element. For instance, if you have normal-motion and reduced-motion themes and want to add the reduced-motion:hover:transition-none class, then you also need to add the normal-motion:hover:transition class (or any value of transitionProperty). If you don't do this, then it will look like the values from a theme that's supposed to be inactive are "leaking" into the active theme.

Fallback

Like when just selectors or just media queries are used for theme selection, the fallback feature for both media queries and selectors serves to "force" a theme match for the None / both Neither case in the active theme table.

Here's an example:

// Rest of the Tailwind CSS config and imports...
plugins: [
    themeVariants({
        baseSelector: "html",
        themes: {
            "not-inverted": {
                selector: "[data-colors=normal]",
                mediaQuery: colorsNotInverted /* @media (inverted-colors: none) */,
            },
            "inverted": {
                selector: "[data-colors=invert]",
                mediaQuery: colorsInverted /* @media (inverted-colors: inverted) */,
            },
        },
        // Since `inverted-colors` has limited browser support, 
        // assume visitors using unsupported browsers do not have their colors inverted
        // and fall back to the "not-inverted" theme
        fallback: true,
        // 💡 Since selectors are being used too, we could even provide 
        // a button on the site that will manually enable/disable inverted colors
    }),
],

It has the corresponding active theme table:

<table> <thead> <tr> <th align="left">Match</th> <th align="left">Neither</th> <th align="left"><code>inverted-colors: none</code></th> <th align="left"><code>inverted-colors: inverted</code></th> </tr> </thead> <tbody> <tr> <th align="left">Neither</th> <td align="center"><code>not-inverted</code></td> <td align="center"><code>not-inverted</code></td> <td align="center"><code>inverted</code></td> </tr> <tr> <th align="left"><code>html[data-colors=normal]</code></th> <td align="center"><code>not-inverted</code></td> <td align="center"><code>not-inverted</code></td> <td align="center"><code>not-inverted</code></td> </tr> <tr> <th align="left"><code>html[data-colors=invert]</code></th> <td align="center"><code>inverted</code></td> <td align="center"><code>inverted</code></td> <td align="center"><code>inverted</code></td> </tr> </tbody> </table>

Call the plugin more than once to separate unrelated themes

The list of themes passed to one call of this plugin are intended to be mutually exclusive. So, if you have unrelated themes, like a set for motion, and another for light/dark, it doesn't make sense to stuff them all into the same plugin call. Instead, spread them out into two configs to be controlled independently:

// Rest of the Tailwind CSS config and imports...
plugins: [
    themeVariants({
        baseSelector: "html",
        themes: {
            light: { selector: "[data-theme=light]" },
            dark: { selector: "[data-theme=dark]" },
        },
    }),

    themeVariants({
        themes: {
            "motion": { mediaQuery: prefersAnyMotion },
            "no-motion": { mediaQuery: prefersReducedMotion },
        },
        fallback: true,
    }),
]

The ultimate example: how I use every feature together

Because I primarily made this plugin to solve my own problems (a shocking reason, I know!), I take advantage of every feature this plugin provides. Here's an excerpt of the Tailwind CSS config I use on my site:

const { themeVariants, prefersDark, prefersLight } = require("tailwindcss-theme-variants");

module.exports = {
    theme: { 
        // ...
    },

    plugins: [
        themeVariants({
            baseSelector: "html",
            fallback: true,
            themes: {
                "light-theme": { selector: "[data-theme=light]", mediaQuery: prefersLight },
                "dark-theme": { selector: "[data-theme=dark]", mediaQuery: prefersDark },
            },
        }),
    ]
}

Usage with the Tailwind CSS Typography plugin

To use theme variants with the official Tailwind CSS Typography plugin, create prose modifiers for each theme and use them in the HTML.

Here's an example of changing the prose colors with themes. This covers all of the color settings in the default typography styles:

const typography = require("@tailwindcss/typography");
const { themeVariants } = require("tailwindcss-theme-variants");

module.exports = {
    theme: {
        extend: {
            typography: (theme) => ({
                light: {
                    css: {
                        color: theme("colors.gray.700"),

                        "a": {
                            color: theme("colors.blue.700"),
                        },

                        "strong": {   
                            color: theme("colors.gray.900"),
                        },

                        "ol > li::before": {
                            color: theme("colors.gray.600"),
                        },
                        "ul > li::before": {
                            backgroundColor: theme("colors.gray.400"),
                        },
                        
                        "hr": {
                            borderColor: theme("colors.gray.300"),
                        },

                        "blockquote": {
                            color: theme("colors.gray.900"),
                            borderLeftColor: theme("colors.gray.300"),

Thanks to @stefanzweifel's article on the subject and @pspeter3's issue!

Now that we have appropriate variants for prose, let's upgrade our HTML to use them:

<body class="light-theme:bg-white dark-theme:bg-gray-900">
    <article class="prose light-theme:prose-light dark-theme:prose-dark">
        <p>
            Content...
        </p>
    </article>
</body>

We will revisit this example in the Semantics section below once I've written that out 😁. Until then, you can reference this plugin's documentation site's configuration as an extremely rough guide.

Semantics

Semantics are an experimental feature for this plugin that serve as a better approach to custom properties. If you're on Tailwind CSS 1.7 to 1.9, this means they still work on IE11!

TODO. Semantic classes bundle up your design system with this plugin's generated variants. Because I (the plugin author 👋) have to write them, only certain utilities are supported so far:

But, when you use the variables feature, you can use any utility as long as you can reference var(--semantic-name).

⚠️ They support variants provided by Tailwind's core and by other variant-registering plugins, but not variants created by this plugin!

Constants

TODO. Constants are the easiest way to get started with semantics. They're called "constant" but actually change with each theme; they're just declared "up front" in the tailwindcss-theme-variants plugin call / configuration. TODO. Constants are declared by specifying a value from your theme configuration for each configurable utility in the semantics option for each theme in themes, like so:

themeVariants({
    themes: {
        light: {
            mediaQuery: prefersLight,
            semantics: {
                colors: {
                    "body": "white",
                    // Use Tailwind CSS's default palette's 800 shade of gray
                    // (unless you overrode it in your regular Tailwind CSS theme config)
                    "on-body": "gray.800",
                },
            },
        },
        dark: {
            mediaQuery: prefersDark,
            semantics: {
                colors: {
                    "body": "gray.900",
                    "on-body": "gray.100",
                },
            },
        },
    }
}),

Now you have classes like bg-body and text-on-body that represent light:bg-white dark:bg-gray-900 and light:text-gray-800 dark:text-gray-100 respectively at your disposal! Because you can now write semantically named classes, this feature is called semantics.

Examples

TODO

Variables

TODO. Variables are an optional extension on top of constants. If you specify target: "ie11" in your Tailwind config, then they will be excluded, reducing the generated CSS size.

⚠️ Don't give the same semantic name to multiple utilities in semantics; when using variables, they'll collide because they share a global "namespace". TODO: make this not the case.

TODO. Every semantic name also has a corresponding variable. Each variable defaults to the active theme's constant declared in its semantics configuration. Variables are automatically used by the semantic utility classes, so you don't have to do anything special to make them work.

For that reason, you can also assign values to semantic variables with the typical custom property syntax

--semantic-variable: 0, 128, 255;

To maintain compatibility with the text-opacity, bg-opacity, etc, utilities, write semantic colors as r, g, b.

Examples

TODO

Custom semantic utilities

TODO. Just like you can write custom stacked variants, you can write custom semantic utilities. Pass utilities, an object of named utilities to SemanticUtility interface-compatible objects.

Alternatives

Both because there are many theme plugins for Tailwind CSS, and because what's the right way to do theming? is a frequently asked question, we've compiled this table listing every theme plugin to compare their features and ultimately answer that question.

This table is complicated, so a text summary is also available in tailwindcss-theming's Alternatives section.

Legend

Responsive: While "inside" of a theme, it must be possible to "activate" classes depending on the current breakpoint. For instance, it has to be possible to change background-color when both the screen is sm and the current theme is dark.

Supports prefers-color-scheme or other media queries: Because any media query can be detected in JavaScript, any plugin marked as not supporting prefers-color-scheme could "support" it by adding or removing classes or data attributes, like the prefers-dark.js script does. This approach still comes with the caveats that

  1. JavaScriptless visitors will not have the site's theme reflect their preferred one
  2. It could still be possible for a flash of unthemed content to appear before the appropriate theme is activated (unless you block rendering by executing the script immediately in head)
  3. Your site will immediately jump between light and dark instead of smoothly transitioning with the rest of the screen on macOS

tailwindcss-prefers-dark-mode and built-in dark mode: cannot use selectors and media queries at the same time; it's one or the other, so you have to put a ✅ in one row and ❌ in the other.
