This is DOM Level 2 (but that's not an official Component): If the font property is set in a given ruleset in the stylesheet, and then I set font-family through the DOM, the change doesn't do anything. If I instead set font-family (and other longhand properties), things are fine. As I said on www-dom, I think the statement now in Interface CSS2Properties on shorthand properties should really be in setProperty and getPropertyValue. If you go with that statement, this behavior is wrong. Examples to be attached, both working and broken, since I'm going to change the original page.

Aargh. It has nothing to do with the shorthand properties. I didn't do what I thought I did when I was testing. It just doesn't work if the property is already set in the element, whether shorthand or longhand. Once this is fixed, you might want to use these examples to test the shorthand properties, though. I'll still make the other attachments.

One last thing - to see the problem, type in a font name that is on your system, and hit the "Display" button.

Cc:ing Peter Linss. I'll take a look at it and see if there's anything I can do before passing it on to Peter (who's away for the next 2 weeks).

Passing this along to Peter since it's a style system problem and I swamped with my own.

The bug here is in the test case's script. The section: var j = 0; while ( ( i < styleSheet.cssRules.length ) && (styleSheet.cssRules.item(j).type == 1) && (styleSheet.cssRules.item(j).selectorText == cssSelector)) { j++; } should really be: var j = 0; while ( ( j < styleSheet.cssRules.length ) && (styleSheet.cssRules.item(j).type == 1) && (styleSheet.cssRules.item(j).selectorText != cssSelector)) { j++; } Note the wrong index variable and reversed equality test of selectors. The script is simply setting the font on the wrong style rule "div.contain" rather than "div.contain p" so the setting is being overridden by the "div.contain p" rule. This can be verified by dumping the style sheets in viewer

Verified invalid, including the original report on shorthand properties.
