have a question... Is there things that you can do to your stylesheet to optimize a sites performance? Does it make things faster to combine statements rather than having many multiple statements? Here's an example of what I'm trying to get across here...

#something1, something2, something3{
border-image 0;
}
or

something1 {border-image 0;}
something2 {border-image 0;}
something3 {border-image 0;}
which of these ways is the fastest?.... or does it even make a difference?
Thanks for your time everyone...
