P is for Paragraph <p>
The paragraph is the workhorse of a text-based website.
Things to remember. Between the opening <p> and closing </p> tags
the browser will only recognise a single white space (one spacebar
click) between characters. If you want more you need to use the non-breaking
space entity ( either
by name - - or by number -   ) in your source code
as many times as you want white spaces.
There is also the in-line break element <br> which is used without
a closing tag </br> in HTML but with one in XHTML.
The difference is this. When word processing you hit the return key
once to go to the next line (in HTML use <br>). You hit it twice to
go to a new paragraph (in HTML use <p>).
But in Dreamweaver, for some reason, when you hit the return key in
Design mode (WYSIWYG) it does a double carriage return, i.e. creates
a new paragraph.
Nvu, an excellent and totally free cross-platform web authoring tool,
works more like a word processor - or should I say even more like a
word processing programme. When you have bodytext selected in the format
drop down menu, the return key does a line break <br>; when paragraph
is selected it starts a new paragraph.

alive and doing good work in cyberspace!]
