An h1 Heading

Here is a div element. A div can contain any other block elements, and thus is useful for grouping together content that should be handled collectively
Here is a second consecutive div element. Note how there is no extra space between these two blocks

An h2 (align="right") Heading

Here is a paragraph. Paragraphs have extra space above and below them, unlike div's. The same is true of headings, addresses and blockquotes.

Here is a second paragraph with align="center"

Here is a third paragraph. Note how the margins above and below paragraphs are bigger than the line spacing. This paragraph has the attribute align="justify". Note how the text is justified between the left and right margins. This is not very useful, however, if the font size is large relative to the width of each line. And now, another brilliant quotation from Jack Handey:

I can still recall old Mister Barnslow getting out every morning and nailing a fresh load of tadpoles to that old board of his. Then he'd spint it around and around, like a wheel of fortune, and no matter where it stopped he'd yell out, "Tadpoles! Tadpoles is a winner!" We all thought he was crazy. But then, we had some growing up to do."
