Just curious, so I figured I'd ask... when I'm using mixins, I want them to be reusable for different elements. You're including a height and margins in the mixin, which leads me to think you'd just reuse the css class if you wanted those specific dimensions to be reflected. Is there something I'm missing?
No, you're definitely right, I plan on putting a little more work into this. I think the margins are needed (would need to experiment a bit to know for sure lol) but colors and height should definitely not be hard-coded in the mixins.
Just making sure. Very cool and useful regardless!
Refactored this a bit, it's a little more configurable and reusable now and you were right about the margin (it's included in the screen.scss for display purposes, but not necessary in the mixin). You have to generate the stylesheet with Compass to see the results on the HTML page, but here's a screenshot.
Definitely a cool effect.

Disclaimer: I totally stole this from @nrrrdcore (the
apple-shadow.cssfile is from her original gist), this is just a rough translation to SCSS using Compass mixins. 😁
