Trying to get border of an element using css method works only in Opera and Chrome. IE8+ and FireFox gives NaN or nothing (IE10). The same is with older versions of library

From ​http://api.jquery.com/css/:

[Retrieval of] Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: $(elem).css('marginTop') and $(elem).css('marginRight'), and so on.
