EDIT: ... or do you know some css optimizer that crosses the selector and css properties together?

Answer 1

You can remove /*\*//*/ form.contact legend { display: inline-block; } /* IE Mac legend fix */- even Microsoft does not support Mac IE anymore.

Answer 2

First of all, delete all css-hacks and place them in other browser-specific files, which you will include through conditional comments .

Answer 3

Cleancss.com, , . . , !

Answer 4

: 0 0 20px 0; - 0, , .

-, css, Google (, http://flumpcakes.co.uk/css/optimiser/). . .., , . , , , .

, , reset.

It seems to me that CSS seems pretty compact.

Answer 5

You have 5kb cacheable , gzippable CSS, which will be even smaller if you separate comments and spaces . Trying to optimize farther than I don't think is actually worth more than 3 seconds of your time.

Answer 6

On #botton

border-color: #69C; 
border-style: solid;
border-width: 1px;

can be written more concisely since

border:1px solid #69c;
