A change to use percentages and 'em's instead of hard pixel widths or font size would achieve a more fluid layout. Basically, always use em for font size. Only use px when you know the exact dimensions of something (like setting a negative margin for a graphic)
To really get what you want (a responsive layout that is designed to work well in print and a variety of devices), you should use the 'media' selector, in combination with 'media queries' [1]
CSS like the following would be good:
@media (min-width: 55em)
{
.main
{
float: left;
width: 65%;
margin-right: 5%;
margin-bottom: 1em;
}
.aside
{
float: left;
width: 30%;
margin-bottom: 1em;
}
}
Note how both columns are floated "left" which means that when your math or the browser isn't broken and the percentages <=100% they are side by side. This side-by-side layout is only applied to devices that have a screen width of 880 pixels [2]
