Answer 2

If you want to learn HTML, CSS and Javascript then go to this web page:

www.w3schools.com.   It is free and very good. Web Site: https://www.w3schools.com/html/default.asp

Advise>  You can use any text editor to write HTML code but I use Visual Studio Code. Itis a Free program.   I use Two Screens.   I have Visual Studio Code up on one screen and the page I am working on on the second screen. Makes it easier to see the results.

Before you upload you web page check it for mistakes with a free service;
