Sphinx7 multiline signatures contain very wide line spacing that is not changeable.

[lvthanh03]

Problem

Cannot change line-height through custom theme CSS:

Project to reproduce

Set maximum_signature_line_length = 1 in Sphinx conf.py. Generate any python docs.

Error Logs/Results

Other themes show much more reasonable line-height, or give the ability to change line-height.

Environment Info

• Python Version: 3.8.10
• Sphinx Version: 7.1.2
• RTD Theme Version: 1.3.0

Possibly fixed by #1450? In the meantime, I've found adding some custom CSS does fix this for me:

/* Take out pointless vertical whitespace in the signatures. */
.rst-content dl .sig dl,
.rst-content dl .sig dd {
  margin-bottom: 0;
}

/* Make signature boxes full-width, with view-source and header links right-aligned. */
.rst-content dl .sig {
  width: -webkit-fill-available;
}
.rst-content .viewcode-link {
  display: inline-flex;
  float: inline-end;
  margin-right: 1.5em;
}
.rst-content .headerlink {
  position: absolute;
  right: 0.5em;
}
