Get a box with zero depth including some text

Question

How to get a box including some text in text mode, which depth 0pt?

Answer 1

You can use \raisebox to modify the official height and depth of some text:

\raisebox{0pt}[\height][0pt]{<text>}

This raises the text by 0pt (so not at all), keeps the official height identical to the original height and sets the depth to 0pt.

Answer 2

\smash{great} is a box with zero height and no depth

Answer 3

I don't know exactly what you want to do but if you want a special box with special dim then you can try :

\newbox\mybox
\setbox\mybox=\hbox{}
\ht\mybox=10mm \dp\mybox=0pt \wd\mybox=20mm

But If you put some text in your initial \hbox, you can have some strange results ! When you make a box with some contents, height, depth and width depend of the context.
