Welcome To My First HTML Document.

Up to now I have learned, among other things,
1. what tags are,
2. that an HTML document is made up of tags and their contents,
3. the structure of an HTML document consists of the HEAD and the BODY parts.

Everything seems to be very clear. I am even writing my first document.

Oh Ya, now looks more like it except the indentations before the numbers. I havee ven added a horizontal line at the end. But, Why aren't the spaces before the numbers not showing? I hope I will get the answers soon.
