Okay, so, let's say you have some data like this:

$things = [
  0 => [ 'id' => 123, 'title' => '123 Title', 'content' => '123 Content' ],
  1 => [ 'id' => 456, 'title' => '456 Title', 'content' => '456 Content' ],
  2 => [ 'id' => 789, 'title' => '789 Title', 'content' => '789 Content' ],
];

Less mixin to calculate vertical rhythm styling for headings [in Bootstrap]. Don’t ask me how this works because I don’t remember and this made my brain hurt enough.
View headings.less

line-height: unit(@line-height * 2, em);
