I’m trying to add a horizontal line to fill the space similar to h(1fr). However, it seems I cannot specify a relative length to line. Ultimately, I’m trying to achieve something similar to this.
Thanks, a box with a fractional width is what I’m looking for.
I tried to create an MWE, but I already had two approaches: one with grid and another with only h. I wasn’t sure if using either would muddle the discussion, when it feels like I just missed some components/functions.
