In the User Guide for CS6, in the chapter on ePub export, it says:
"Specify a simple margin in Ems or pixels. Specifying margins in Ems is
better for multiscreen compatibility."
I do not see any choice in the Export ePub dialog for specifying ems as
the unit of choice for the margins. Also, typing "1 em" gives an error.
Have I missed something?
I believe that's a documentation error. There seems to be no such option.
It seems so. Thanks for confirming that, Steve.
Thanks for pointing this issue out, and am sorry for the confusion it caused.
I'll have a look and update the documentation accordingly.
