What is the default padding and/or margin for a p element (reset css)?

Question

I have been using a reset CSS set of styles for quite some time now and each time I got to create a new website, the reset the annoys me the most is the reseting of a p tag

Answer 1

To even things out across browsers , I use

p{
  margin:0;
}
p + p{
  margin-top:10px;
}

this way I dont "brake" containers original top/bottom spacing and still space the paragraphs nicely if there are more than one.

I just dont like to see p pushing parent containers like this

.container {
  border: 1px solid #ccc;
  padding: 15px;
}

and see this as ideal solution

.container {
  border: 1px solid #ccc;
  padding: 15px;
}
p{
  margin:0;
}
p + p{
  margin-top:10px;
}
