Yes, for fonts (excuse me, I forgot to mention).
**@TheDoc** & **@CrocoDillon** thank you!
I looked over the sites I’ve seen and studied how to use em, but can you tell me the benefits of using less em? I mean, yes, I understand, to the pixels that are fixi, em is flexible, so to speak, do not get stuck as pixels, but more specifically what help? Help create a responsive template? If you could give me, please, some more specific examples than.
P.S. : @CrocoDillon – Why prefer rem? Is better than em or just like you used?
