Add HTML Elements to XUL Addons
I've been working on a new addon at Mozilla which isn't anywhere near finished so I wont bother telling you what it's meant to do...because it could change at any moment. Since this is my first real addon, it's been a struggle, but that's a good thing -- it means I'm learning a ton. One problem I ran into was trying to get a checkbox (INPUT) element within the addon via JavaScript -- nothing was displaying.
After a bit of research and guesswork, I figured out what I was doing wrong -- I was using the wrong document method to create the element:
var input = document.createElementNS("http://www.w3.org/1999/xhtml", "input");
Using document.createElementNS with the proper namespace resulted in my checkbox displaying in all of its glory. It's beautiful square, checked glory. Firefox addons can be created in a number of ways so if you're looking to create your own and you aren't seeing HTML elements correctly, keep this solution in mind!

One major problem with creating UI components with the MooTools JavaScript framework is that there isn't a great way of allowing customization of template and ease of node creation. As of today, there are two ways of creating:

![Dynamically Load Stylesheets Using MooTools 1.2]()
Theming has become a big part of the Web 2.0 revolution. Luckily, so too has a higher regard for semantics and CSS standards. If you build your pages using good XHTML code, changing a CSS file can make your website look completely different.
![PHP / MooTools 1.2 Accordion Helper]()
The MooTools Accordion plugin seems to be the plugin that people seem to have the most problems with. It's an awesome plugin, so I can see why so many people want to use it, but I think that may be part of the problem.
Reminded me of my initial days with JavaScript David! I also made the same namespace errors and then wondered for hours, what went wrong!
