$(a).css('background') return empty string

[gaetan]

$(a).css('background')

return empty string.

But the setter

$(a).css('background','some value')

works.

I use

$(a).css('background-image')

to have the good value.

In the documentation, since 1.0, background is not supported, but it works for me until 1.3.2.

(Firefox 3.6.12 && Google Chrome 5.0.375.70)

Element :

<a href=​"#​" style=​"background:​url(image.png)">link</a>

As you stated yourself, the documentation for  css() is clear about this:

Shorthand CSS properties (e.g. margin, background, border) are not supported.
