compass-sass, css, mixins
Solution
SASS Example
@import 'compass/css3/filter'
.filtered
@include filter(grayscale(50%))
@include filter(blur(2px))
Problem
I'm trying to use filter mixin this way in SCSS: ``` a { @include filter(grayscale(100%)); } ``` But when I compile, I got this error: ``` Undefined mixin 'filter'. ``` I'm using the latest version of this Gem with Rails framework. http://compass-style.org/reference/compass/css3/filter/
