Hi! I'm currently learning basic HTML and I wanted to know what was the best way to study/practice so I don't forget it.

Lots of practice. Just use the stuff repeatedly as you're learning. First, get yourself a text-editor for your coding. I recommend sublime text 2 or 3, but you can use whatever you like. Another popular choice if you're running windows is notepad++.

Anyway, just open up your text editor and begin coding. Save it as an html file and just use that as a running file of notes. That's what I did initially. Every lesson I took I actually then went in to my html doc which was actually titled html_notes.html and I would apply what I learned and actually write about it in an article format as if I were writing an article to teach someone else. It sounds a little weird at first right? You're just learning so why would you be teaching it? Well, take it from me, the best way to learn something on a deeper level is to teach it as soon as you can. Just remember, no one is gonna see your file, it's not there to be perfect, it's there for you to ingrain the stuff that you're learning and the best way to do that is to actually practice the examples and explain what you're doing.

The best thing about this is you have to code all your text with the appropriate tags as well so while you're learning you're actually creating your first webpage of sorts that you can always look back on and go "wow, I've come a long way."

It will evolve and get better and you'll love seeing the new sections every day and how much you've improved.

Another little tip... don't just learn something like lists and then go and build a list and go "ok, I know lists now.". Build a list and delete it. Build another one and delete it. Build another one but then style it. Delete it. Build a new one, this time an ordered list. Style it. Mess with the styles. Delete it. etc...

If you're not on the CSS part yet, don't worry about styling it just yet. Just build a bunch of lists and keep deleting them. Try nesting lists inside of lists. When you learn some new element or whatever on here, go on over to MDN and read up on the element. See what you can do with it and mess around. Then build some stuff with it in your evolving document.

Whatever you choose, just code code code! :)
