Sunkanmi Fafowora is a frequent flier around here. You’ve probably seen his name pop up in the CSS-Tricks Almanac and we actually just published something today that he wrote up for the color-mix() function. The guy spends a lot of time in the Almanac because he loves technical documentation, something he showed off when writing the CSS Color Functions Guide.

And it’s that love for technical documentation that lead him to ship CSS-Questions (gotta love that hyphenated URL, right?!), a place where you can test your CSS knowledge with over 100 questions. You can take the comprehensive exam or a basic one with 20 questions if all you want is a pop quiz.

And of course, the first question I get is related to CSS color functions!

Question 1: What color model does oklab() improve upon?
You’re just trolling me now, aren’t you Sunkanmi?!

My first try was a valiant effort, I’d say…

Almost perfect. Could be the title of my autobiography.

CSS-Questions originally published on CSS-Tricks, which is part of the DigitalOcean family. You should get the newsletter.
