Line high between heading and paragraph - css

Question

I have the problem that my headings overlap. Here an example. I know that the problem is the line high that is set to 0:
h3 {
line-height:0;
letter-spacing:1px;
}
If I use line high:1 the problem disappears, but the space between the heading and the paragraph becomes too large and the page does not look very nice.
So what I would like to do is to have line high:1 for the heading and line high:0 for the space between the heading and the paragraph.
I hope anybody has a solution.
Thank you!

Answer 1

Just add margin-bottom of about 5px to your h3 heading
p {
margin:0;
padding:0;
line-height:1em;
}
h3 {
line-height:1;
letter-spacing:1px;
margin-bottom: 5px;
}

Answer 2

I tried this in your JSFiddle example and it seems like what you want:
h3 {
line-height:1; /* put 1 here */
letter-spacing:1px;
margin-bottom:0px; /* add this line */
}
