Jesus Christ, that's a lot of CSS.

Well, right off the bat, I can tell you can shrink the code by quite a bit by setting the properties in one declaration. Glazing over it, you should be able to do this for background, padding and margins, and mabye more. Should decrease the size abit.

It could be usefull if you provided HTML together with this CSS. For me it is too big to start optimising without appliance. I need to SEE what you try to do in this way to be able to suggest alternatives.

After all can someone help?

[vgarcia]

Start using shorthand CSS. For example, instead of:

p.lila {color: #000; font-family: arial, verdana, helvetica, tahoma, sans-serif; font-size: 0.9em; font-weight: bold; font-style: italic; text-align: center; background-color: #fff}

Try:

p.lila {color: #000; font: bold italic .9em arial, verdana, helvetica, tahoma, sans-serif; text-align: center; background: #fff}

See the difference? Multiply that for every rule you have in your stylesheet and the file savings will add up. Use smarter selectors instead of a class for everything and you'll see still more savings in both your HTML and CSS.

Yah, thats what I recommended too vgarcia. However I think he wants us to do it for him
