Remove grey area in comment form

Hello! I would like to remove the grey area in my comment form. It’s the bit that comes between the words “log out” and the actual comment form itself. http://www.w3joy.org/

I have a child CSS sheet, and I found this on the forums:

#comments {
width:90%;
}

#respond textarea#comment {
height:80px;
}

Which helped reduce the WHOLE box (great) but did not eliminate the line.

Then I tried inspecting with firebug and changing the padding to ‘0’.

#respond {
background: none repeat scroll 0 0 #DDDDDD;
border: 1px solid #D3D3D3;
border-radius: 3px 3px 3px 3px;
margin: 0;
padding: 0;
position: relative;
width: 68.9%;
}

And I tried making this 0.

#respond p {
margin: 0;
}

Still, there is a large grey area btwn the comment-box-title-text and the actual form.

Anyone know the CSS to reduce/eliminate this?

Cheers,
Squirrel
