designMode
Every once in a while I stumble upon an API or browser setting that I can't believe ever existed. Such examples can be seen in the numerous String.prototype properties such as bold, italics, and even blink, which wrap given string text in their representative HTML tags. Bizarre.
It was recently brought to my attention the document.designMode API: an on|off switch that acts almost like a contentEdible attribute for the entire document. You can toggle designMode by simply changing the setting:
document.designMode = "on";
With the designMode setting on, you can edit page text, drag and drop assets, and generally cause chaos on the page. This is really nice for prototyping; I'd have loved to have known about this while doing client work.
While I see uses for this API, it does feel a bit bizarre. I'd have liked to have known the origins of this property and its use cases. Have ideas about how you'd use it? Share!

![Regular Expressions for the Rest of Us]()
Sooner or later you'll run across a regular expression.

But what if you could decode regular expressions and harness their power? In...
![MooTools Zebra Tables Plugin]()
Tabular data can oftentimes be boring, but it doesn't need to look that way! With a small MooTools class, I can make tabular data extremely easy to read by implementing "zebra" tables -- tables with alternating row background colors.

The above CSS is extremely basic.
![Sliding Labels Using MooTools]()
A week back I saw a great effect created by CSSKarma: input labels being animated horizontally. The idea is everything positive: elegant, practical, unobtrusive, and requires very little jQuery code. Luckily the effect doesn't require much MooTools code either!
