I mostly read programmer books which tend to have code blocks (I'm not sure what the ePUB standard says, but I'm guessing it's something like <code>let ABC = 123;</code>)

In print form, and in some other eBook readers, these blocks would use a monospace font

I noticed in Myne that they do not e.g. go to the Hello World chapter in this ePUB that can be dowblaoded here: https://golang-for-python-programmers.readthedocs.io/en/latest/about.html#resources

Describe the solution you'd like

I'd love for Myne to use a monospace font to render the contents of these blocks, and it might also be necessary to preserve white space (for indented code as intended by the author)

How will you/everyone benefit from this feature?

I believe this would help Myne users read and enjoy any content that makes use of code blocks
