So you want do make code, don't you? Well, for Html5, get out of this website, you troll and visit http://www.w3schools.com/html/default.asp. I'm not a teacher. They're the world wide web's interactive teaching course and are very helpful. I'm not.
But I guess I can help a bit. You need to start every code
with what I have at the top, the <!Doctype html>.
Then you need <html>.
Followed by <head>.
In the head, you put the <title>e, which is the thing you see when you hover your mouse.
Then you close the head the same way you opened it but like this </head>
Then in the body you put a <p>. You put your content in that, it will show up in the website. DON't forget to close everything, including the body, the html, but NOT the DOCTYPE.
