Learn2 large whitespace on blank page

Hey all,

I'm trying to get a site set up with the Learn2 theme but I'm running into a bit of an issue. On some pages that are just folder redirects, the theme leaves a large blank space after the page title. When trying to make this whitespace go away with CSS, it has no effect. Looks like it's due to page sizing of some sort.

In which file is this page sizing controlled in the theme? Or is this controlled in normal page settings outside the theme? I just want the color scheme to be consistent.

For my CSS, I'm already using the following to try to recolor the container:

body #sb-site,
body .sb-site-container {
  background-color: #3d424e;
}
