CodePen is another cool learning tool. Not exactly a class, but you can see what other coders do in html, css, and javascript and see the code and the result.

Also, if you are visual person (like me), get into css grids. It will give you a lot of satisfaction and not feeling overwhelmed by all the markup.

That said, age makes no difference. Everyone should learn, and now is the best time, because code has come a long way. Nowadays, there are a lot of free learning sites, and that’s great!
