WordPress.org

I know how to increase the page size using the code below and increasing the width.

#page {
margin: 20px auto;
padding: 2;
width: 760px;

How would I go about setting it so the sidebar text moves to the right and the main content spacing goes farther to the right. Basically, the exact same thing I have now, just...wider.

Also, how would I go about creating a space between the top banner and the main page that contains links to various pages. I'm aware that the space is found in the code below, but sadly that's all I know.

#header {
background-color: #000;
