I think you should start to do your own CSS and HTML projects right away , you will learn more building stuff.
Wes Boss and Kevin Powell have a few courses for free. I would start with Grid (Wes Bos) and, even at the same time, you could follow Conquering Responsive Design by Kevin Powell, wich cover some basics and flexbox. But Grid is better now because will help you with almost every layout, and then you could check for specific problems in mdn web docs or w3schools How to section, for instance. O just watch more Wes Bos or Kevin Powell videos. Remenber than mdn web docs has all you need to learn frameworks as well. They cover a lot of tools and technologies.
Or even you could do The Odin Project, they will teach you some basics about a few things (Git, GitHub, web, …) and then you will start with HTML, CSS and JavaScript, with exercises and small projects as you go.
As you start to feel comfortable building sites you could start JavaScript curriculum as well, it takes time to complete when you have zero knowledge in programming, as me.
Just my opinion and some ideas. But focus in a few projects for a couple of weeks, for example, because that will help you to fix CSS and HTML knowledge, and go deep, and start to thing in build you own Portfolio too.
Happy coding!
