960.gs and other CSS Frameworks use the padding and margins, all you have to do is to override them

this is the normal code

<div class="span-18">
    <div class="span-4 last">
    </div>
</div>

use something like

<div class="span-18 cut-margin">
    <div class="span-4 last cut-margin">
    </div>
</div>

and

.cut-margin { margin-right: 0 !important; }

and set the new width of your elements to the element + the margin/padding you are using.

You can always create your own bigspan classes, for example:

.bigspan-4 { width: 475px; margin-right: 0px; }
.bigspan-18 { width: 715px; margin-right: 0px; }

and

<div class="bigspan-18">
    <div class="bigspan-4">
    </div>
</div>

remember that you can always design your onw grid
