Reduce spacing between consecutive <dt> elements

[FloEdelmann]

What are you trying to accomplish?

See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/dt:

multiple <dt> elements in a row indicate several terms that are all defined by the immediate next <dd> element

Example usage on GitHub: https://github.com/tummychow/git-absorb/blob/master/Documentation/git-absorb.adoc

Currently, those are separated by a 1rem margin, making them look like separate definitions (without a description):

What approach did you choose and why?

Reduce the spacing between consecutive <dt> elements to zero:

This is a similar approach to consecutive <li> elements and makes definition lists more readable.
