A simple sass file providing standard easing functions for css transitions. It is based on compass-ceaser-easing extension but without the compass dependency. This make it compatible with libsass.
@import "sass-easing/stylesheets/sass-easing";
.transition {
transition: all 4.2s $easeInOutQuart;
}
Since it doesn't rely on compass you will have to handle vendor prefixes with autoprefixer for example.
