Its el.hidden = true; in modern browsers

The documented semantics of the hidden attribute say otherwise https://developer.mozilla.org/en-US/docs/Web/HTML/Global_att... http://www.w3.org/html/wg/drafts/html/master/editing.html#th...

" it is incorrect to use hidden to hide panels in a tabbed dialog, because the tabbed interface is merely a kind of overflow presentation — one could equally well just show all the form controls in one big page with a scrollbar"

I'm curious - is this spec'd anywhere? I just tried it in Chrome and it works great, but I couldn't find it in any of the specs for Element or Node.

According to specs mentioned elsewhere, it seems to have reasons to exist other than just display hide/show purposes.

It's easily overridden by CSS.

el.style.display = 'none' pretty much works everywhere.

To me, it seems to depend upon what the purpose of hiding/showing the element is in specific cases.
