Best free text HTML, CSS, PHP courses?

So, I'd love to start my own small Internet blog, and I want to make it without any extra software, just plain HTML+CSS, maybe some PHP for convenience.

I have near-zero experience in programming (yes I know HTML is not programming language, but you get the point), and I just finished a wonderful starting guide, HTML For People. I loved it a lot, but it only covers the absolute basics, and I'd love to have a deeper dive.

Are there any HTML, CSS, PHP guides that are free, text-based (so, not YouTube videos), and give more than the very basics? Would love to hear your recommendations!
