A few utility classes have been added to sscaffold, mostly imported from milligram to improve compatibility with existing milligram installations.
This class should be added to an element containing a full-width table due to webkit's lack of support for
max-width on tables. This issue is further detailed here.
This common utility class, also found in milligram, has been added for improved drop-in compatibility with existing sites.
.float-left and .float-right
These classes have been added from milligram also. Because they do nothing more than add a
float: left or
float: right rule to affected elements, it makes more sense for these to be handled in a theme stylesheet or in the site's custom stylesheet.
