- Bounding box for each letter 4 answers
I'd like to use a sequence of boxes to show how TeX works. I read some time ago that everything (or almost) in TeX are boxes.
So, how to show only the TeX boxes that surround each character, each line, each paragraph?
I'd like something similar to the image below, not
fbox which contains blank space around it.
