Kf - Sass Keyframe Animation Library

Kf is a SCSS library which makes composing CSS keyframe-based animations simple.

A single @import away; Kf lets you define animations in a simple SCSS map format and then modify and compose your animations together using a collection of self-explanatory mixins. Kf takes care of the laborious work of translating your animation into CSS keyframes, freeing you up to focus on your animation itself.

You can use Kf for creating anything from simple button hovers to intricately timed and sequenced animations spanning over multiple elements (once only thought feasible by using javascript). Install via NPM or get the single-file import to get started.

Live demos available at:

Overview of Kf

• Modular / composition-focused SCSS animation library
• Available as a single SCSS file @import (no dependencies)
• Great and simple for quickly for creating animations
• Documented through examples at kf-sass.com
• Well-thought out design (mixin-composability, animation-map flexibility etc.)
• Small readable source-code & plently of unit tests

Installation & Basic Usage

Grab the single-file distribution release or install via NPM:

npm install --save kf-sass

Next, include in your SCSS file:

@import 'relative/path-to/kf.scss';

From here the most basic example would look like:

.sliding-box {
  $animation-map: ('div': ( margin-left: ( 0ms: 0%, 300ms: 30%, 2000ms: 100% ) ));
  @include kf($animation-map);
}
