First of all this post is intended for people that are new to playing with the DOM (document object model) The DOM is the structure in a web page.
Specifically I've posted this for my IS450 (Web Development Class) and TiddlyWiki friends though feel free to comment on any additions.
Before using any tools, I'd recommend getting a bit of knowledge under you belt.
The major tip is that if you are coding a page do the following: make it work using Firefox and its corresponding tools, then make it work in Internet Explorer.
I'll put up more stuff after class.
