CSS Question: Is this legit / supported / compliant?
I'm wondering if duplicate / overriding directives are allowed in the CSS Spec.
Here's an example:
Code:
<div style="background-color: black; background-color: white">


will the second call to background-color override the first and be drawn as white?

it may sound stupid, but i'm writing a PHP class that outputs CSS and I don't want to have to do pattern matching to make sure that the user inputted tag isn't already set. I want to just append it.

The CSS validator at w3c.org does not return an error nor a warning when you re-declare a style like you have.

interesting...
i thought i read somewhere a long time ago about the proper way to override a style by re-declaration, but i think it had something to do with using linked style sheets and embedded sheets in the header. It didn't mention anything about doing it inline like I have here.

You don't want to use JavaScript to set the style?

i came up with a pretty basic solution. i just split the tags by ; and then again by :. That gave me a keyed array an consequently weeded out the duplicates.
