ShadeCycle

Gradient text shadow functions and mixins in SASS.

Demo

Getting Started

npm install shade-cycle

Import the SCSS file:

@import 'path/to/node_modules/shade-cycle/dist/shadecycle.scss';

Use

You can use ShadeCycle anywhere you'd use a text-shadow or box-shadow.

The SASS function for creating a ShadeCycle is as follows:

shade-cycle(num_layers, offset_horizontal, offset_vertical, start_color, end_color, repeat?, offset?)

• num_layers: number of layers to show
• offset_horizontal: relative offset of each layer (x axis)
• offset_vertical: relative offset of each layer (y axis)
• start_color: color to begin with (closest to text)
• end_color: color to end with (furthest from text)
• repeat?: optional number of times to repeat the color transition relative to the number of layers. If you set this value to 2 or 3 and the layers to 10 you'll see the transition repeat for example. Setting to zero or leaving out will transition smoothly between start and end colors without repeating.
• offset?: optional number of iterations to shift from the original color. This will start at a color in-between the start and end, and when the end is reached ShadeCycle will begin from the start color again. This is mainly used in animation.

Animations

One SASS mixin is included right now to do animations: shade-cycle-animation. You can also write your own mixin that takes advantage of the shade-cycle function.

SASS syntax:

@include shade-cycle-animation(num_layers, offset_horizontal, offset_vertical, start_color, end_color, repeat, milliseconds)

All parameters are required here. The one that differs is the milliseconds parameter:

• milliseconds: Length of the animation in milliseconds before the it repeats.

A known issue with the animation is that if the offset and layers aren't set close to each other the keyframes that are generated aren't very smooth.

Contributing

Clone this repo. If you want to edit the documentation site, npm install. I'm using Aurelia for that. Otherwise, the dist/shade-cycle.scss file has all that you need.
