I own all the books by Heydon (their webbed briefs videos are also worth a watch!) and I've also bought the Eleventy course by Andy. They're both excellent chaps and great educators as well. Andy was also one of the persons behind the revamped content on Google's https://web.dev https://web.dev. They both truly demonstrate how to build robust and accessible websites with properly structured elements and how to tame obscure layout quirks. I recommend perusing the content they produce. If I can suggest a few more people, I can also strongly recommend Max Böck and Manuel Matuzovic as well.
