If you haven’t heard of
theme.json yet or you don’t know what it does for WordPress themes, then this post from Tammie Lister will inspire you to learn. She notes this is “the first major theme process change to core in years.”
The Block Editor Handbook has a big, beefy page devoted to
theme.json that will get you up to speed. 🥩
theme.json separates style from form (layouts) and starts us down a path where designers eventually will have all the tools they need to build themes without developers.
According to Tammie, “It’s not quite there, but eventually no-code themes will be possible.”
