Any suggestions on how to add whitespace above a question?

In survey.css,

.Question {
font-size: 100%;
color:  #6582A9;
}

I've tried adding padding-top and margin-top to no avail.

EDIT:

Found the answer. I had to create a new css property in survey.css. In case anyone else run into this, this is what I added:

.Question td {
padding-top: 20px;
}
