m hapter 11 shows how you can use free WordPress themes in your blog. ^^ Many people are quite happy to use these themes without making any adjustments to them at all. I can't tell you, however, how many times people have asked me how they can customize a theme that they've found. The answer to their questions is always, "Of course you can make changes on your own."
The practice of changing a few elements of an existing WordPress theme is tweaking. Thousands of WordPress blog owners tweak their existing themes on a regular basis. This chapter provides information on some of the most common tweaks you can make to your theme, such as changing the header image, changing the color of the background or the text links, and changing font styles — and these changes are pretty easy to make, too! You'll be tweaking your own theme in no time flat.
Before you go too wild with tweaking templates, make a backup of your theme so that you have the original files, from which you can easily restore if you need to. You can back up your theme files by connecting to your Web server via FTP (see Chapter 6) and downloading your theme folder to your computer. When you have the original theme files safe and secure on your hard drive, feel free to tweak away, comfortable in the knowledge that you have a backup.
