Well I attempted to update the theme of this site to one of the available options. I was looking for one with a default dark or night mode since the white is hard on my eyes. Nikola makes this fairly easy, run the command to download the desired theme, alter one or two lines in the conf.py file and it's done. Except github gave me an error on trying to rebuild the page and to try again later. So Ill have to see if it was just a hiccup in their system or if it just doesn't like this particular theme. If it continues to cause problems I'll have to look at using the custom css option or forking a theme to modify.
