Demo to see how the theme looks in a sample Drupal site Apply theme


The very first idea is to have a theme that removed Drupal's unnecessary markup, focus on Mobile First.

Sonambulo is a base theme for Drupal 6, with clean markup & CSS, simple and lightweight. Less divitis, more fun, and say yes to HTML5 on Drupal 6!!

Like other blank canvas base themes, this theme will NOT make your site look sexy, but Sonambulo will help you clean up the excessive markup that Drupal provides out of the box.

Sonambulo’s default layout is a mobile first, responsive layout with a fluid grid system, based on 960px. Sonambulo is responsive - if you add the basic layout css and create your own breakpoints. ;)

Intended audience

Themers who doesn't like the markup & CSS options that Drupal provides out of the box.
