Hidden

Welcome dear HTML5-er. You will be able to read this paragraph, but not the next. The next paragraph has the hidden property set on it. It's a boolean that uses the browsers own stylesheet to hide the element, which is nicer than having to dip in to the style properties in JavaScript.

Sadly, your browser doesn't support the hidden property. Useful when you want to quickly do element.hidden. Ah well, back to CSS.
