Fix: #719 Fix literals going over page width

[Blendify]

THis should fix the literal example on https://sphinx-rtd-theme.readthedocs.io/en/stable/demo/demo.html#inline-markup

Fixes: #719

[jessetan]

This changes all inline literals ato block level elements, so that they fall on the same line. I don't think we'd want that.
white-space: normal; seems to be better suited. It will cause literals that fall outside of the page width to wrap.

Closing in favor of #1050
