Sassy-Gridlover

Super easy to use Sass mixins to establish a typographic system with modular scale and vertical rhythm. Based on the Gridlover app.

Gridlover gives you adjustable CSS for font sizes, line heights and margins. The default CSS output is for html, body, h1-h6, p, ul, ol, etc. but you can of course apply your adjusted values to any element by editing the CSS later.

First of all

Go play around with the awesome Gridlover app!

It's so much fun! 😄

Installation

Install Sassy-Gridlover via bower.

$ bower install sassy-gridlover

Install Sassy-Gridlover via npm.

$ npm install sassy-gridlover

Install Sassy-Gridlover via yarn.

$ yarn add sassy-gridlover

or Download the repository and include the sassy-gridlover folder to your Sass directory.

Getting started

Sassy-Gridlover consists of 7 configurable variables:

$sgl-base-font-size;
$sgl-base-line-height;
$sgl-base-unit;
$sgl-scale-factor;
$sgl-debug-mode;
$sgl-debug-mode-max-width;
$sgl-extras;

and 4 mixins:

@mixin sgl-html();
@mixin sgl-body();
@mixin sgl-heading();
@mixin sgl-margins();

These are the 4 functionalities of the Gridlover app that you (should) have been playing with ;)

Setup

Import _sassy-gridlover.scss to your main style sheet.

@import "sassy-gridlover";

Change the configurable variables values in _config.scss to your liking.

I would encourage you not to change them directly here, though. It would be better to declare them in your _variables.scss, _config.scss or the like.

Mixins

By default, all the mixins (except sgl-html) will output em. But you can also choose to output px, rem or pxrem.

`sgl-html()`

This mixin is mandatory for the all the other mixins to work.

To use on <html>.

Outputs font-size and line-height always in px.

html {
    @include sgl-html($font-size: $sgl-base-font-size);
}

Parameters

Name	Description	Type	Default value
`$font-size`	Root font size.	`Number`	`$sgl-base-font-size`

`sgl-body()`

To use on <body>.

Outputs font-size and line-height.

body {
    @include sgl-body($line-height-step: 0, $unit: $sgl-base-unit);
}

Parameters

Name	Description	Type	Default value
`$line-height-step`	Multiplies the step number by the base `line-height` (from `sgl-html`). If `0` is set, it will actually multiply by `1`.	`Number`	0
`$unit`	Unit to output (`px`, `em`, `rem`, `pxrem`).	`String`	`$sgl-base-unit`

`sgl-heading()`

To use on headings <h1> - <h6>.

Outputs font-size, line-height, margin-top and margin-bottom.

@include sgl-heading($font-size-step, $line-height-step, $margin-top-step, $margin-bottom-step, $unit: $sgl-base-unit, $base-value: $sgl-base-font-size)

Parameters

Name	Description	Type	Default value
`$font-size-step`	Creates an exponent of the base `font-size` (from `sgl-html`) in conjunction with `sgl-scale-factor`. `0` is the base `font-size`.	`Number`	-
`$line-height-step`	Multiplies the step number by the base `line-height` (from `sgl-html`). If `0` is set, the `line-height` will grow with the `font-size` accordingly.	`Number`	-
`$margin-top-step`	Multiplies the step number by the base `line-height` (from `sgl-html`).	`Number`	-
`$margin-bottom-step`	Multiplies the step number by the base `line-height` (from `sgl-html`).	`Number`	-
`$unit`	Unit to output (`px`, `em`, `rem`, `pxrem`).	`String`	`$sgl-base-unit`
`$base-value`	Optional parameter for a different base font size when using `em`.	`Number`	`$sgl-base-font-size`

`sgl-margins()`

To use on <p>, <ul>, <ol>, <pre>, <table>, <blockquote>, etc.

Outputs margin-bottom and margin-top.

@include sgl-margins($margin-top-step, $margin-bottom-step, $unit: $sgl-base-unit, $base-value: $sgl-base-font-size)

Parameters

Name	Description	Type	Default value
`$margin-top-step`	Multiplies the step number by the base `line-height` (from `sgl-html`).	`Number`	-
`$margin-bottom-step`	Multiplies the step number by the base `line-height` (from `sgl-html`).	`Number`	-
`$unit`	Unit to output (`px`, `em`, `rem`, `pxrem`).	`String`	`$sgl-base-unit`
`$base-value`	Optional parameter for a different base font size when using `em`.	`Number`	`$sgl-base-font-size`

Debug mode

Enables/disables debug mode.

Outputs background lines imitating a notebook's sheet.

Parameters

Name	Description	Type	Default value
`$sgl-debug-mode`	Enables/disables debug mode.	`Boolean`	`false`

Declare it in your own _variables.scss, _config.scss or the like. Basically, it must be declared before the @import "sassy-gridlover".

Example

Outputs extra reset styles.

Parameters

Name	Description	Type	Default value
