Comment

I truly wish that CSS had a single-line comment sequence. Every other language I know does but good old CSS doesn't, as far as I know.

e.g.

div#header
{
 background-color: #000;
 /* background-image: url(/images/backgrounds/header.png); */
 background-repeat: repeat-x;
 height: 50px;
}

That is how you comment in CSS, /* at the begining of the comment block and */ at the end. // sadly doesn't work.
