There’s two places that padding is adjusted. One is in the Stylesheet.
Under the general section
section {
padding-top: 75px;
margin-bottom: 0px;
overflow: hidden;
The bottom margin is the operational factor.
The other place is in the functions.php. Search for the following line:
.page-template-main-template-php .section-page
and then set the padding you desire right after it – e.g.:
{padding:35px 0;}
That should do it for you.
