Developing a Web Page

These past couple of weeks my class has learned how to develop a web page. We have learned that web pages are made in HTML format. To do this, you need to put your work on the notepad and the file must be named "index html" in order for it to save correctly.
Some of the work we have done has been challenging for me to understand like the amount of codes that you need to know. They are all similar and it is sometimes confusing.
The website http://www.w3schools.com/ has helped me tremendously during this time. This website helps you understand the codes and teaches you the correct way to use them.
