Hi, to match my page to the different resolution, which is the better option? setting min.width or doing a align/float center?

And also, which part of my css table should I edit to make everything (esp the header) to float center? So what happens is that when someone is on a smaller resolution, it will look full-page while if you have higher resolution, there will be white bars at the side. is the the best way to solve the resolution problem? It should be like yahoo.com in that sense

To float center, you use css

margin-left: auto;
margin-right: auto;
