title: See the page outlines
body: <p>Is there a tool that allows to see the whole page oulined in the browser? For example, I have a lot of hidden divs or images, may be overflown by some other elements and I want to see all the elements outlined, just to see what is placed in what place. If you ever used Adobe Illustrator, you could understand what I mean if you switched to outlines mode there by clicking CTRL+Y. I use FireBug now for something like that, but may be there is something more advanced for that?</p>
