Need a lightweight, imageless CSS solution for two-toned borders (like the one above)? So did we! So we jammed together a border & a box-shadow.
Sample code
<h1>Two-Toned Border with CSS3</h1>
<style>
h1 {
border-bottom: 1px solid #025;
box-shadow: 0 1px 0 #fcfcfc;
/* you'll need all the vendor prefixes for `box-shadow` */
}
</style>
It's pretty extendible. You can plop them on any side you want, you just have to do some math. There's more about 2-toned CSS borders in the blog post or View Sass. Enjoy!
