Modify A WordPress Theme
Themes are used to change the look and, in some cases, operation of your WordPress blog. There are thousands of themes to choose from and one might be close to what you want, however, sometimes you just want to move, delete or add something.
In order to modify a theme, you must have FTP access to your server, an editor (ie. Notepad, Dreamweaver), and some knowledge of CSS.
Search for, install and activate the theme which is closest to what you want your final product to look like.
Use your FTP client to get a copy of your current theme. It will be in [wordpress directory]/wp-content/themes/[active theme].
