In this section we will explore – briefly – some of the building blocks of a WordPress theme. In order to use WordPress successfully and have a professional website or blog, it is not necessary to venture further into this section!
However, if you want to tweak your site or break into the wild and wooly world of theme development/child theming, this section will get you started.
For more advanced training on how to develop a theme, you might try Chris Coyier’s video series Designing for WordPress. There’s also a great web tutorial from Themeshaper: How To Create a WordPress Theme: The Ultimate WordPress Theme Tutorial.
