I see you suggest using font-size and line-height in pixels in replies to several questions on this forum. Here is one example:
Please see response to items 5, 6, and 8 in in this example.
1) Is there a particular reason for using px? Is it possible to use em for font-size and rem for line-height instead of px?
2) Does one have to make any other change to the code if one wants to use em for font-size and rem for line-height?
Thanks,
Sam
