Subject: Re: [css-d] [OT] EMs vs. PERCENTs
For box sizing, em is still the font-size. But percent is relative to the
container. If you want the box size to change with the font use ems. (ex.
if you have a box that you want to always display 3 lines of text then set
it to 3.6em -- the height of a line is generally 1.2em, unless you
specifically set it to be otherwise)
If you want the box to change size with the screen, use percents (height:50%
is 50% of the parent container - sometimes the window, sometimes something
else, never the font-size)
--
GREAT explanation!
So, is it uncommon, or bad practice, to use both in this situation?
{height: 7.2em; width: 20%;}
To give you a menu with six lines (no matter what size type) but still only
occupying 20% of the parent container so it scales with window size.
