It’s hard to learn about features you’re unfamiliar with on MDN. There are times that I read MDN docs and think “who is this for?” You can read two paragraphs and not even get an idea of what the feature is supposed to do or what problem it solves. If you’re not intimately familiar with the topic you’re not going to get anything out of reading it.

Sometimes it’s better just to read the spec because there’s more background information.

I’m glad that MDN exists, but I also wish it explained topics as well as CSS: The Definitive Guide. I failed to learn CSS the MDN docs for years before reading CSS: The Definitive Guide. I was up to speed in about three months. Everything made perfect sense.

I’d love to get a wiki that has the explanations of CSS: The Definitive Guide, kept up to date with the reference material of MDN.

I’d pay for this.
