Here are two WordPress theme tutorials:
- What is a WordPress Theme? – A WordPress theme provides all of the front end styling of your WordPress site. Most WordPress themes provide the overall design or style of your site, font styling, colors, widget locations, page layouts (or templates) styles for blog posts and blog archives and additional stylistic details.
- How to Install a WordPress Theme – In addition to the default theme included with your WordPress installation, you can also install your own WordPress theme to change the look and style of your site.
