Alignment attributes can be added to the <p> tag to align the text in a paragraph to the left, right or center (though large chunks of text are rarely aligned right or center).

So if you were to write this in your HTML doc:

<p align=left>I fear my bathroom window. It opens to
an airshaft, and when it's hot outside I leave it open.
Unfortunately, if it's hot enough for me to open the
bathroom window, it is also usually hot enough for
my neighbors to open their bathroom windows.


<p align=center>I can hear everything. I can hear
them argue, and I can hear them flush the toilet.
The heat is bad enough; I don't need to know
whether or not Elaine upstairs thinks Jeremy
should shave his goatee.


<p align=right>When I moved into the bigger, cheaper
apartment next door, I couldn't shake the
memory of the wild summer parties I'd
overheard. It took me four weeks to even
<i>think</i> about using the bathtub. I scoured
it until it gleamed, showered, and attempted to
sleep. I couldn't. So I asked that it be replaced.

You might consider moving. Oh, and your page would appear like this:

Of course, you can use paragraph tags for text that's shorter than a full-on paragraph. For instance, you may want to center some words, like so:

<p align=center>If someone offers you
<p align=center>a breath mint,
<p align=center>take it.

They'll appear like this:

If someone offers you

a breath mint,

take it.
