When you say "front end development", what exactly do you mean? Because that will strongly influence what you need to learn. If you mean "JavaScript Programmer" then it'll be mostly JS focused, some tooling, some html and css but minor on those. If you mean a true frontend dev then you'll need a LOT more on CSS (Flexbox, Grids, box model, etc) and a bunch of UI/UX/HCI type reading in addition to learning in depth modern HTML and CSS and Javascript. If you mean "I want to learn HTML and CSS" then you'll just want the first half of the previous one. So I'm curious as to what you're looking for. I'd be happy to recommend reading lists, tooling, etc. I've been doing frontend work for 20 years (and now also do a lot of JS on the server) so I've got a grounding in this! Just let me know what you're looking to do and I'll help any way I can.
