Quick Website Presentation + code

First of all I noticed that the video quality is not so good for some reason

I'm showing some things I've made on my first dynamic website, using what I've been learning so far in about a year of experience. I'm making this website mainly in PHP and JS, with CSS as well.

As I said above, this is my first dynamic website, meaning that this is the first one linked to a database with real registration system etc. The last one was a static one because I've started learning PHP a month ago, in early September
