Based on CSS Drop Shadows by Nicolas Gallagher
A bunch of CSS classes and SASS mixins for creating resolution-independent crisp and visually appealing shadows without using any images.
Yup, check out the 10 various shadow types here: http://ahrengot.github.com/sass-dropshadows/
As a SASS mixin:
div {
@include shadow('curved');
}
Using the CSS class names:
<div class="shadow curved"></div>
