We didn't used to have a lot of standards around the way things looked in the admin UI (historical technical reasons for that). We can do better now, and really clean this up. A few things immediately stand out here:
Too much padding around this, compared to other pages. Likely coming from the existing security center classes, or default element styles. We can probably fix this up by adding some better rules for the classes being used.
There's a max width enforced, but there's not much reason for that. Let's get rid of that.
It'd be nice to have that indented part have the same level of "indentation" as the outer container, once the above is fixed up. We actually have LessCSS constants for all this, so we can keep things nice and consistent.
