Extruded text in pure CSS

A Sass function generates a stack of text-shadows that reads as solid depth.

How it works

  1. There is no real depth here — it is many hard-edged text-shadows, each offset 1px further.
  2. Darken each layer slightly and the stack reads as a solid side wall.
  3. Finish with one blurred shadow for the drop shadow on the "ground".
  4. In Sass a @function with a @for loop writes the list for you (see the Sass source tab).
