This file has some CSS that limits the form width to 70%, and then gives 30% of that to the form labels and 60% to the form controls.

Basically the same CSS is provided by Standard/Clean etc. to lay out all standard moodle forms so this is redundant.

At least this can be deleted:

.path-admin-tool-customlang .mform.filterform

{ width: 70%; margin-left: auto; margin-right: auto; }

.path-admin-tool-customlang .mform.filterform .fitem .fitemtitle

{ width: 30%; }

.path-admin-tool-customlang .mform.filterform .fitem .felement

{ width: 60%; margin-left: 31%; }

And someone might want to have a second look at the rest of the file, bearing in mind that this CSS is now sent to every user of Moodle (which might not have been the case when originally written) and the fact that the default theme has changed so much. Perhaps we can delete most of it.
