Whats is it

Delay.css works best along with Daniel Eden's Animate.css, by including CSS classes and helpers to control animation timmings and delays, but it works on any kind of CSS animations as well.

In other words, it is possible to add sequential animations or increase the duration of a particular animation using only a tiny helper class.

But we can also do this with CSS3, why add this?

Because of the same reason we have Animate.css, it is just easier to implement something that has already been done and tested than create something from scratch.

TL;DR

Delay.css was created to help you control your CSS animation timmings within a project.

Installing

$ bower install delay.css --save

It also works with npm:

$ npm i delay.css --save

Using

First of all, add the css to your document's head:

<head>
  <link rel="stylesheet" href="delay.css">
</head>

Then select the desired duration or delay.

Delay.css is divided into 100ms blocks that goes from 100 to 6000 (100ms to 6s) of timming control, and two simple classes .delay-<ms> and .duration-<ms>.

This can be easily adjusted if you need less or more timming control (as you will see in the next section). Each class will delay the start of the animation by the amount of miliseconds it describes. So the class .delay-100 will delay the start of the start of the animation by 100ms and .duration-100 will force the animation to have 100ms long.

This can be easily adjusted if you need less or more timming control (as you will see in the next section).

To use it, just add the corresponding classes to your elements, for instance:

<div class="animate fadeInDown delay-1200"> <!-- This will happen first -->
  <h1 class="animate fadeInUp delay-1500">This is a header</h1> <!-- This will happen 300ms after the div has appeared -->
</div>

Try it out in your css, or see it in action.

Custom builds

To add or remove timmings from your customized version of this project, just go to the src folder and modify the file called delay.scss.

There will be 3 Sass variables, $i (which stands for increment, do not touch this!), $maxms which will be the max time your delay/duration will have and $hops which, of course, will be the size of the "jumps" between values.

Example:

$i: 0;
$maxms: 7500;
$hops: 500;

The same goes for LESS files, just change the delay.scss to delay.less and the $ to @

Will generate a file containing .delay- and .duration- classes that goes from 500 to 7500ms jumping in ranges of 500ms each.

.delay-500
.delay-1000
.delay-1500
...

As this uses Sass, you'll need to build it using your own sass compiler or running the gulpfile included in the project when you download it, just type npm i (if you didn't install the dependencies) then gulp and it will create a dist folder with your alterations.
