Easy HTML Builder is a free tool for programming beginners.
It features tools for multiple frameworks, currently: Bootstrap and MaterializeCSS, and a HTML preview.

You can click on the button and it will insert the code snippet pre-configured by a pop-up window into the area you click in, this way
you learn something.

TO-DO:
