Center
<center>
</center>
With the center tag you align center almost anything.
Use it before any text or image you want to center on the screen.
Paragraph
<p>
</p>
The p tag starts a new paragraph.
It also inserts a blank line space between the next element.
You can also align paragraphs left, center or right.
<p align="left">
<p align="center">
<p align="right">
Left is default on most browsers so no alignment tag is needed.
If you use the "center" tag before your paragraph all your text will be centered.
Div Alignment
<div>
</div>
Align element blocks with the div tag.
<div align="left">
<div align="center">
<div align="right">
Left is default on most browsers so align left may not be needed.
Vertical Alignment
valign="top"
valign="bottom"
valign="middle"
Middle is default on most browsers so align middle may not be needed.
