If you want to really learn it and master it, I'd advise you start with a project to build something you'd like. With that in mind, learn a programming language. JavaScript, CSS and HTML will be a good start for the frontend. You'll then need some backend skills. You could learn MySQL and JavaScript will also help you develop the back end. Along the way, you'll figure out a lot of the stuff yourself. Avoid using AI at all costs if you really want to learn. Once you've mastered the skill, AI will be a multiplier. Good luck
