Creating webpages by html

I've been simply making and posting websites by using iWeb of Mac.
However, I did not know what html files are about.

This is great that I learn how to do with html, and how websites are created.

As a novice web-maker, I had difficulty understanding
the concept of the file in the beginning,
but as I work and create a variety of webpages with html,
I am now familiar with html and feel very confident.
