After looking at (dynamic-theme) I had an idea.
“Wouldn’t it be cool if you could have a different theme for each season and wouldn’t it be even cooler if the seasonal theme changed depending upon whether or not it was daytime or nighttime?”
Since I thought this would indeed be cool the next step was to put a prototype together. This GitHub repository (all-seasons-theme-webext) is the result.
This is my first attempt at creating a WebExtension so I am sure it is rough around the edges, but I welcome feedback, just please, keep it civil and remember I am still learning.
Please excuse and forgive me if this topic was posted in the wrong section. My thinking was that this relates more to Add-on Development (specifically WebExtensions) than to Themes even though this is asking about a WebExtension Theme.
