1. Browsers are inconsistent in the way they round div sizes in percent-based layouts. If the browser must render a number like 144.5px or 564.5px, they have to round it to the nearest whole number. Safari and Opera round down, Internet Explorer rounds up and Firefox rounds one column up and one down filling the container completely. These rounding issues can cause inconsistencies in some layouts. In this IECC there is a 1px negative margin to fix IE. You may move it to any of the columns (and on either the left or right) to suit your layout needs.
2. The zoom property was added to the anchor within the navigation list since, in some cases, extra white space will be rendered in IE6 and IE7. Zoom gives IE its proprietary hasLayout property to fix this issue.
