The development of an open-source theme is a strange kind of collaborative effort. Without personally knowing all the people I have benefitted from, I would like to thank them.

The concept for a layout geared towards classical typographic principles grew over some years out of many already existing ideas. I can’t even mention every helpful author I read about typography and CSS techniques. Many conceptual parts date back to Matthew Butterick’s beautiful online book Practical Typo­graphy. It also taught me a lot about typography in general and some about distinctive American-English features.

Without Chris Coyier’s always up-to-date website CSS-Tricks I would have been lost in the CSS specs. He and all his contributors have been clarifying the constantly evolving capabilities of CSS like only a few others.

Perplex includes IBM’s font family Plex because these fonts have been designed specifically for technical writing and publishing. Thankfully, IBM is improving and releasing them as open source.

Perplex ships with slightly altered SVG sets of Google’s Material Symbols. There are thousands of them and they come in various shapes which makes them one of the most versatile open-source icon sets available.

Most images in this documentation were made available free of charge by numerous skilled photographers on Unsplash. Their names and a link to the source are given in the captions.

Last but not least: Only thanks to Hugo and its active and incredibly helpful community I could realize this theme. I owe special thanks to Steve Francia for bringing Hugo to life, to Joe Mooring for his numerous precise suggestions and examples, and of course to the long-time project leader Bjørn Erik Pedersen for his ongoing enhancements and insights into this marvelous software.
