Zentropy is a flexible, highly-optimized and Responsive HTML5 Base Theme which attempts to bring the best of a couple worlds together:

  • Full HTML5 markup, including ARIA roles
  • Mobile-friendly, responsive approach
  • Highly optimized, building on established techniques
  • Built by themers, for themers
  • WCAG 2.0 level AA compliance
  • Holy Grail layout (no grids™)
  • Nice Drush integration

It includes efficient, resetted, layout-driven CSS and markup that is acessible, search engine optimized and doesn't get in your way.

Try it out, you will find it a joy to use Zentropy!

Main Features

  • It converts the core template files to HTML5 markup (based on Boron - all credit to Scott Vandehey (spaceninja) of Metal Toad Media)

  • It is responsive! Borrowing from the Responsive HTML5 Boilerplate theme and 320 and Up, implementing media queries for progressively larger screens

How many release candidates are we going to have before 7.x-2.0 stable?

Simply put: as many as we need!

The theme is pretty stable as is but might not quite there yet (although many have been using it in production with great results). Please help test it and file issues to make this a SOLID release! Thanks!

These are the issues blocking a 7.x-2.0 release

#D7AX - I pledge to make this theme as accessible as it can be. If you find any flaws, please submit an issue. Help me fix them if you can.


The maintainers provide consulting services and paid development, e.g. for implementing a specific feature. Help improving the theme and get in contact!
