Easing Equation for SASS/SCSS
A list of easing cubic-bezier functions derived from Robert Penner's easing equation. Code was taken from the LESS-CSS3-Mixins github repository and then converted from LESS to SASS/SCSS.
Usage in a Compass project
// easing.scss
@import "easing";
.button {
@include transition(400ms $easeInOutBack);
}// easing.sass
@import easing
.button
+transition(400ms $easeInOutBack)
