This is my first made-from-scratch web page, written in HyperText Markup Language.
It's fairly simple, but not everything seems to work as expected.

Heading Size #2

I think I'll put a horizontal line in here:

Heading Size #3

Ok; let's try a SHORT line:

This line is followed by a line break tag,
This line is followed by a paragraph tag.

Here is another line break tag,
This is another paragraph tag.

This is Heading size 3

Now Let's try some Graphics work!

Let's see if text will wrap in between these two graphics. What do you know!!! If I delete the middle image and align the images to the left and the right, the text fills in the middle as long as there are no paragraph breaks. That's COOL!!! If I want to move the rest of my text below the images, I can use the code "br clear="all" /"
What if I want an image in the middle of a line? Will this do it?
