WestCiv provides some really useful tools and examples of CSS in action. For example, you can make an [http://www.westciv.com/tools/gradientsnustyle/index.html#background-image:%20linear-gradient(%20#ffffff,%20#000000%2010px,#000000%2025px,#ffffff%2035px,#000000%2045px,#000000%2060px,#ffffff%2070px) 'equals' background effect].

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' <ref>good list of various approaches at https://gist.github.com/dustinboston/3867516 </ref>
CSS like the following would be good:
<source lang="css">
@media (min-width: 55em)
{
.main
{
float: left;
width: 65%;
margin-right: 5%;
margin-bottom: 1em;
}
.aside
{
float: left;
width: 30%;
margin-bottom: 1em;
}
}
</source>
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 <ref> 55em translates to 880px for the browser default font size of 16px. https://css-tricks.com/css-font-size/</ref>
