Sure 🙂
Try modifying the code above to something like:
[code].asp_main_container {
margin: 0 auto 26px auto !important
}[/code]
..where the 26px is the bottom margin, you can change that to anything you want.
Also, if I may suggest another thing. I noticed that the theme is adding a bit of a box shadow inside the input field when focusing it. If you want to get rid of that light grey shadow, you can use this code:
[code].probox .proinput input:focus {
box-shadow: none !important;
}[/code]
