No Formatting in Posts?

in your css you have:

* {
margin: 0;
}

That removes the default margin from everything. I don’t see where you’re resetting the margins for paragraphs. First off move this to the top of your CSS file as any margins you declare before it will be over written.

I don’t know how much havoc it would cause to remove it entirely so maybe just do something like:

p {
margin: 0 0 12px 0;
}

to give the paragraphs back some margins.
