In Level 1 we introduce the anatonmy of the theme and the files you'll find within. We walk through creating your own basic theme and introduce the concept of sub-theming.

In the "evolution of a themer", this is where the fun really starts. Up until now you may have downloaded a contributed theme from Drupal.org, maybe you hacked the theme a bit to make it your own but you've never made your own theme. This blog post is all about reaching Level 1 and creating your own basic theme from scratch.

What is a theme?

By definition, a theme is a layer in Drupal which styles and formats your output right before it's put on the screen. The theme gives you one last chance to change something before your visitors see it. Themers have ultimate control of the website because they're in control of that output.
