This is an example of a heading 1 line

And this is h2

This is just plain text. Notice that when I display it on the screen, extra lines are taken out. The extra stuff is whitespace, and I can type it any way, but the browser will put the text all together.

This is a heading again, after a horizontal rule. Both the br and hr tags are single tags. Most others are paired...

for example. Some tags have attributes which alter the way the attribute behaves. See the body tag attribute bgcolor (background color). This attribute changes the color from white, its default, to yellow. Book contains "web safe" color palette in the back.
