One of the units of measure that CSS recognizes.  In theory its the size of the 'M' 
character for the current font face and size.  In practice it... usually is.  Its also 
generally accepted as a better unit to use than px (pixels) if you want content to resize 
itself nicely to fit different display sizes.  (What looks nice at 50px on my screen, 
might be either invisibly miniscule or awkwardly huge on someone else's.  At 10em it'll 
usually look much the same on mine and theirs.)
