[css] Is there an opposite to display:none?

visibility:hidden will hide the element but element is their with DOM. And in case of display:none it'll remove the element from the DOM.

So you have option for element to either hide or unhide. But once you delete it ( I mean display none) it has not clear opposite value. display have several values like display:block,display:inline, display:inline-block and many other. you can check it out from W3C.
