HTML Help

My experience with HTML has been very positive. It seems to have a good learning curve for beginners, then when you start to get into CSS it gets more advanced.

These three websites helped me to learn HTML.

w3schools

w3schools.com

On this site you can learn a lot of different types of coding languages, and it seems to be a favorite of the schools.

Developer.mozilla.org

This site you can learn HTML, CSS, and JavaScript.

GeeksForGeeks.org

You can learn HTML, and the site is ascetically pleasing.
