Does anyone have or know of an HTML page containing all the elements (with lipsum text or whatever)? I could make one, but I figured someone must have already done this.
A sample page with (almost) all HTML elements can be found at:

I find the Yahoo base and reset stylesheets quite useful for this purpose. They are designed specifically to give you a clean slate and are based on w3 guide lines. It is also worth looking at their grid and font css tools.
I hope this helps.
