After the div on line 30 is moved (mentioned in the next comment), this <if>
should go before line 23.
Then the "block" can be removed from <div class="settings-box block first"> on
line 23.

This could be moved out of the div on line 23.
Then this div would change from 
<div class="layout horizontal center">
to <div class="settings-box continuation">
That will allow this div to get the proper height and layout from settings-box.

It looks like the "block" should be removed on line 43 and a </div><div
class="settings-box continuation"> added around line 50. That would allow lines
44 and 51 to simply be class="start" and remove the need for
.inherit-min-height.
