Theme Development

HTML themes to Backdrop themes

I've been meaning to write up a blog post about how to go from a HTML template (purchased from a place like to a Backdrop theme. As a developer with only a smidge of design skill, I have found this to be a workable alternative to hiring a designer for custom work.

Below you'll find a very a rough outline of the steps I follow:

My first theme for Backdrop CMS

I tasked myself with rebuilding my dad's old Durpal 6 site,, to Backdrop CMS in one weekend.

I decided to rebuild from scratch rather than upgrade so that I could test more of Backdrop, and catch and fix bugs in the process (I found a handful - all now have PRs in the queue). After the site was built, I then needed to recreate the theme.

Respect for all the hard work done by the Drupal community

I started by opening an issue on in the queue for the old Drupal 6 theme, Aeon5. I asked politely if the current maintainer would be interested in working on or maintaining a Backdrop CMS version of the theme. It is, after all, their work, and they should be aware of what's going on, even if they aren't interested in being involved.
