By chance I stumbled across an old device with an outdated browser and decided to go with an entirely new approach for the theme of this blog.
The motivation was support for this device, which led to reanalyzing the whole concept of only using modern techniques. An article on this will follow in the next weeks.
The new design and Codebase is much more functional and simple, focusing on content and support for the most devices possible.
While the series on creating this theme is still an interesting read into the things I tried, it is now outdated and I would not recommend following it for the actual styling.
If you are interested in setting up the build system for a theme than it is still relevant.
If you find any bugs, please contact me and I will try to get them fixed ASAP.
