I know the “standard” way to write CSS is like this:

#container
{
    width: 960px;
    height: auto;
    font-size: 14px;

#container { width: 960px;  height: auto;  font-size: 14px; }

However, often times I’m working on an inherited project or using a snippet I found and the CSS isn’t laid out the way I like. I found a site that helped me out with this. The design is wacky but it did the trick. There is a fair amount you can customize so you should be able to mass convert any CSS to the way you like it. On a downside, I think it strips out all comments…
