CSS
I just recognized that this is the first ever post on CSS I do here. This will change. With macOS 10.14.4 Apple released Safari 12.1 which supports the prefers-color-scheme media query. This can be used to provide a the user with either a dark or a light user interface depending on the operating system setting. So I decided to implement it for my blog.
Since I changed my blog to a darker color scheme based on Dracula a few months ago, I thought it might be a cool feature to bring back the old (red & white) color scheme to people with a light user interface.
