1 Element CSS Rainbow Gradient Infinity

I first got the idea to CSS something of the kind when I saw this gradient infinity logo by Infographic Paradise: The original gradient infinity. After four hours and some twenty minutes, of which over four hours were spent on tweaking positioning, edges and highlights… I finally had the result below: My vers...

Dark theme in a day

Marcin Wichary has written a great piece that dives into how he used CSS Variables to create a night mode and high contrast theme in an app. There’s so many neat tricks about how to use CSS Variables (Chris has also looked at theming) as well as how to organize them (Andras Galante has an interesting take on this) in...

Simplifying CSS Cubes with Custom Properties

Autoprefixing with CSS Variables

I’d call this a bonafide CSS trick, courtesy Lea Verou. Don’t miss the comments, in which Sérgio Gomes reminds us this might make it easier to change values in JavaScript, because you could skip worrying about prefixes there. Changing CSS variables in JavaScript is already rather appealing, as the changes ...
