[hoangvu]

I reviewed some website and realized that some classes contained 2 class in it
eg :

<div class="class1 class2">...</div>

does anyone explain me about this ?

Thanks

It will combine 2 classes together (class1 + class2) to use all css stylesheet in these classes

Might I add, this is EXTREMELY useful when you're applying browser fixes to existing elements. For example, many times you need to implement a IE width fix to an element. To do this, you would apply the original style ID to the first one, and a second ID with the fix to the second one. Once this is done, you'll have a clean DIV that fixes both the first and the second.

Give this a try by using "tony's fix" on Google. It should work very well for you.
