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.

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