Hey, I’m new to Rails and Ruby in general. I was wondering if it’s possible to use an embedded ruby css file (css.erb), similar to using html.erb files for views.
For example, I’m using
<%= stylesheet_link_tag "main" %>
to link to my main.css file in public/stylesheets, but when I change the file extension from main.css to main.css.erb, it no longer renders the css..
Is this even possible, or is there a better way?
I dont think so. Whats your intention – to use variables and have them be evaluated at runtime, or “compile” time (meaning like deploy time?). Also, what would be the ERB binding? Would it bind to the controller, like views and helpers are, so that ERB instance would have access to the instance variables set in the controller? I just pose this question as more of a theoretical exercise.
If you want to use variables in your CSS than you can use Haml’s SASS. You dont get access to the controller’s scope but you do get basic variables and looping. Plus other cool stuff like mixins.
