[jQuery] Syntax to subtract CSS width

[jQuery] Syntax to subtract CSS width


Hi,
The documentation seems to be down right now, and I'm trying to figure
out how to subtract a CSS value: $('#myDiv').css('width', '-=20px');
I haven't used jQuery very long yet, but I thought I saw this syntax
or something like it in use somewhere. I can't get it to work though...
Chrs,
Dav
