When I first started using Sass, there was one thing that drove me crazy about it compared to Less. For some reason, including a plain CSS file just wasn't something the compiler wanted to do:
/* Uncaught, unspecified "error" event. (Ignoring local @import of "animate.min.css" as resource is missing.) */
But, annoyingly, the resource is there. So why does the compiler report it missing?
I may never understand the logic behind this design decision, but the solution is to simply omit the
/* Imports animate.css */
This works as of version 3.2.
And for those using Less, here's the equivalent syntax:
/* Import CSS file using Less */
@import (css) "animate.css";
