One of the main attractions for WordPress users is the great themes contributed by the thousands of users around the world. Some of these themes are proprietary and some are free. Using these themes, you can decorate and display your WordPress blog in whatever style you want. Though in general bloggers are happy with customized themes, sometimes to make something different from others, you may want to customize the look and feel of your blog. If that is so, there is no way other than editing the theme files.
