.css() and .animate() should accept "" values

[lrbabe]

Using pure DOM code, after setting the inline style of an element, it is possible to reset it by setting a style property to null. See: ​http://jsfiddle.net/vjMgD/

jQuery doesn't handle null values at all, with .css() and .animate().

I'm -1 on adding support for null, which is not actually supported in IE. We'd have to normalize to empty string and I don't see any added value. Plus, seems it would just confuse people after having told everyone to use empty string since 1.0

With which versions of IE isn't it compatible?

I wouldn't really mind leaving .css() as is, but I would find it very useful to have such feature in .animate().

Your patch normalizes null to empty string. I don't think this is something we want to add, especially if it takes more than one line.

We won't support null.
