While studying some CSS and HTML on FreeCodeCamp, I was trying to figure out how I could exercise some of the skills I was learning. One of the basics of CSS is just changing style of fonts and backgrounds, so I figured why not try and make some program that cycles all of those over and over? I found that making your first extension is very easy, so I tried it. After a ton of trial and error, I made a button that allows you to manually turn it on on a given tab, but you can only turn it off through refreshing it. I’ve added a static feature and the ability to choose (wow!) in v1.2. In the future, I’m hoping to add an option to turn it off once it starts.
