I'd call that a 'prevent the page from breaking' issue.  If you have an 
absolute width for say, the navigation column, and an elastic width for the 
fonts; when the fonts are expanded enough, a long word can overflow the 
containing box and overlap the content in the next box.  Been there, done 
that and it is very ugly indeed.  I like that margins and paddings are in 
px, that makes much sense.  But all basic widths should be of a similar 
type (be it em or % or even px) or layout can die in your lovely css very 
very quickly.
