Full Width Textareas
Working with textarea widths can be painful if you want the textarea to span 100% width. Why painful? Because if the textarea's containing element has padding, your "width:100%" textarea will likely stretch outside of the parent container -- a frustrating prospect to say the least. Luckily there's a quick CSS solution to this problem!
The CSS
box-sizing to the rescue!
textarea {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
width: 100%;
}
Setting the box-sizing to border-box allows the textarea to respect its parent container's padding and border, recalculating what 100% actually means. If the box-sizing were content-box, the textarea would continue to stretch outside the parent container as it would have before.

Feature detection via JavaScript is a client side best practice and for all the right reasons, but unfortunately that same functionality hasn't been available within CSS. What we end up doing is repeating the same properties multiple times with each browser prefix. Yuck. Another thing we...
![Link Nudging with CSS3 Animations]()
One of the more popular and simple effects I've featured on this blog over the past year has been linking nudging. I've created this effect with three flavors of JavaScript: MooTools, jQuery, and even the Dojo Toolkit. Luckily CSS3 (almost) allows us to ditch...

Helps tremendously with mobile development as well and calculation of % width when utilizing this box-sizing.
