[Trinidad] Skinning css @import support and EL support?

[Andrew Robinson]

Question 1) I was hoping to clean up the skin css by having different
css files per browser type as necessary. Example:

skin.css:
  @agent ie {
    @import url(ieOnly.css);
  }
  DIV {
    -tr-rule-ref:selector(".ImportMe:alias");
  }

ieOnly.css:
  .ImportMe:alias {
    background-color: yellow;
  }

The "@import" doesn't seem to be working though. Is there anyway to
accomplish this in a skin to have per-browser CSS included in a main
css?

Question 2) Is EL allowed in the skin? Example:

font-size: #{bean.userFontSize}
