 Tastefejl is a fork of the [Typo] Hugo theme, with the following changes:
 
+* Replaced the JavaScript theme switching code with a CSS media query.
+
 * Removed [Simple Icons] because I don't want to plaster brands on my website and at one point a 50MB .html file was committed
   (I filtered the git history to reduce the size of the repository.)
