4.1.2.2. The align attribute
Most browsers automatically left-justify a new paragraph. To change
this behavior, HTML 4 and XHTML give you the align attribute for the
<p> tag and provide four kinds of content justification: left , right , cen-
ter , and justify .
Figure 4-2 shows the effect of various alignments as rendered from the
following source:
<p align=right>
Right over here!
<br>
This is too.
<p align=left>
Slide back left.
<p align=center>
Smack in the middle.
</p>
Left is the default.
