I've rigged up this very (very) barebones example of what I was talking about in my post. If you've just loaded the page, no Javascript has run, so this is like you visited without JS enabled. If you click this link, however, it will "enable" JS and magically the DIV disappears and the "show" link appears. Cool, huh? Now your readers without Javascript can still get to your content, and those with JS are able to experience all your sweet effects.
This is a simple paragraph inside the div
And another, just for kicks.
