CSS: “display: auto;”?

Question

You should use:

$('element').css('display','');

That will set display to whatever is the default for element according to the current CSS cascade.

For example:

<span></span>

$('span').css('display','none');
$('span').css('display','');

will result in a span with display: inline.

But:

span { display: block }

<span></span>

$('span').css('display','none');
$('span').css('display','');

will result in a span with display: block.

This is not a problem: in fact, it’s almost always the desired result.
