I am using the caption and subcaption packages to create sub-figures in a document. I have two cases of sub-figures:
- Two sub-figures side-by-side. For this, the captioning is excellent.
- Two sub-figures one below the other. in this case, the first sub-caption appears immediately above the second sub-figure.
How can I configure the sub-captions to include a small space between themselves and the next element in the second case, without messing up the setup for the first case?
The rude way is to stick a vskip explicitly after the first sub-figure. I prefer to avoid this hack.
