The image does not show the whiteboard. I can image eveyything looks double-spaced since every wide element has 1em before and after it. We already have margin rules for elements, so I think we can drop the .wide * margin rule. This will let the default rules work. If you need to force an 1em between the whiteboard and the line in the page, hack it into the template.
Yes. you are correct about width 60em
