I started in 2001. Oh, man... there were specs, and they were all over the place. The amount of "why?!" I asked... I'll never know. Crazy doctypes too. I was impressed with the direction HTML5 seemed to take, but it was a pain in the beginning. I used to have HTML Validator for Firefox to make sure I don't trigger quirks mode, and once HTML5 came out it was really annoying that there was no offline validator for the browser. I mean it's nice to see the warnings and errors on live pages, but back then I didn't always have internet at home, and I had to validate the HTML I was making. 🙃 But I rarely had issues with it. After dealing with plenty of HTML 4, I became confident enough to switch from Transitional to Strict. 😆 And of course it was a bit painful, but what's life if you don't brave it? Boring!

@Sandromatic The validator gives you comprehensive information about anything that doesn't conform with the doctype chosen for an HTML document. Try "w3c validation" and give it a URL to analyze it. That kind of feedback was possible with HTML4, but when HTML5 came out only online validation was possible with that Firefox extension.
