Divide a page in 8 perfect fluid columns?

Question

So I'm trying to divide a page ( in fact just a footer ) into 8 equal fluid columns ( I was aiming for 6 ), and the only way I thought I could do it is with percentage.

I set a percentage of width: 12.5%; to each of the columns ( which are in fact some links set as display: block; float: left;) and it should have worked, but it didn't. I mean the columns or links should have been equally divided in the page but there's still some space there, about 100px ( my screen has 1366px in width ).

So what should I do about that ? How can I divide the links / columns is 8 ( preferably 6 ) equal fluid columns ?

}

Above is a part of all the CSS, but there's where I'm trying to do what I just mentioned.

Problem Solved: extra padding added to the blocks;

No, I won't provide support for IE at all

Fantastic. In that case, you can use display: table (no support in IE7) along with table-layout: fixed (to ensure equal width columns).

Any number of columns are automatically supported, and as a bonus you get equal height columns for free.

Here's a demo with your HTML: http://jsfiddle.net/thirtydot/KusjP/

.navigation {
    display: table;
    table-layout: fixed;
    width: 100%;
}
.navigation > a {
    display: table-cell;
    border: 1px solid #444;
}
