One thing that has always been a struggle is how to perfectly center an object (for example, a DIV) both horizontally and vertically on a page.  The other night I was searching for a better way to do this via CSS instead of using nested tables.  I came across Dead Centre, a website that demonstrates exactly how to accomplish this.  You can see some of the detail on the webpage itself, but also take a look at the source for more details on how this was executed. This provided a truly dynamic design that was 100% CSS-based and works across all browsers.

It’s a bitter battle between the two – which provides the best feature set while maintaining optimal performance?  I’ve tried both, been back and forth, and can’t quite decide for myself.  Have you tried either or both?  Which do you prefer and why?
