We can easily change the font color of any single letter, word or paragraph in our document:

The
actual
contents 
of
the
document

The actual contents of the document

Let's now add some horizontal rulers,

And several differently aligned paragraphs with differently aligned section headings:

<H1 ALIGN="left">Here goes a header of size 1</H1>
 This is a paragraph aligned to the right
<H3 ALIGN="center">Now goes a header of size 3</H3>
 This is a paragraph aligned to the left
<H5 ALIGN="right">And finally, a header of size 5</H5>
 This is a centered paragraph

Here goes a header of size 1

This is a paragraph aligned to the right

Now goes a header of size 3

This is a paragraph aligned to the left

And finally, a header of size 5

This is a centered paragraph

We can also force line breaks into the text:

Here's 
an 
example 
of 
that

Or, in contrary, we can cause the lines not to break:

The lines won't break even when they are so long that the right edge of the browser window is reached, where the text would otherwise wrap around. I don't see any immediate use for that, but I have to tell you about that anyway.

Not only can we change the font color, but also its size and typeface:

Note that the font that you specify might not be available on a particular system, so it might be a good idea to provide a comma-separated list of 2-3 similarly looking fonts, i.e.

If the first font from the list is not available on a system - the second one is chosen, if still not - the third one.
