Using two css files in the same html file

Question

Is it possible to use 2 CSS classes that have the same name for the selectors, etc. in the same HTML file? If so, how do you differentiate between the two when styling elements?

Answer 1

Yes this is possible, simply include two css files in the HEAD section of the document. Any styles set in the first will be overwritten in the second, so say you have this:
First file:

 #something{
  background-color: #F00;
  color: #FFF;
 }

And then in the second file:

 #something{
  background-color: #000;
 }

Then the background color for #something will be overwritten in the second file to black but the color will stay the same since the second file doesn't say anything about it.
