Need help with changing line height of a single line

I’m editing a website with html, and need to insert an empty line of a custom height to balance two div boxes I’m using. I am clearly not skilled with html. To keep the code simple I’m hoping to make this a single line, if possible.

why don’t you use css to add padding or margin to your divs?

but really, when you ask for help, it is pretty difficult to know what you are talking about if you don’t provide a link to your project
