After talking about it for a long time, the main site has richer theming support along with the frequently asked dark mode. Go to KIRUPA and click on any of the colors towards the bottom in the left navigation to pick the style you want to browse the site in:
I’m not finished with the actual styling for the theme picker, but that’s something I’ll fiddle with more in the future. In the meantime, check it out and let me know what you all think. If there are any colors that you would like to see, let me know.
I do plan to write more about this experience on getting theming working on a 23-ish year old site.
