Not sure why the paragraphs are giving you trouble but I would change the following:

body {margin:0px; padding:0px; font: 0.7em verdana, arial, sans-serif;

to:

body {
margin:0;
padding:0;
font-size:0.7em;
font-family:verdana, arial, sans-serif;
}

You don't need to specify a value on any element with a value of 0. Sounds teeny but in the long run will save you typing time etc.
