Any specific reason why you are not using a <pre> tag for this?

Kindle does not support either <pre> or <tt>

But when I tried it, actually it does.
If I use Kindlegen on the <pre> coded text, Looking at the result in Calibre's Inspect, the AZW is identical: <pre class="memo">, while the KF7 has become <tt>.

I would trust the Kindle Publishing Guidelines over a lot of the info on their website (which is typically outdated and/or geared more towards a Word->Kindle workflow).

I attached a test EPUB:

with this CSS:

.memo {
margin-top: 2em;
margin-left: 2em;
text-indent: 0em;
font-family: monospace;
font-size: .9em;
white-space: pre-wrap;
}

pre {
margin-top: 2em;
margin-left: 2em;
text-indent: 0em;
font-size: .9em;
}

The <p class="memo"> you put together looks fine in KF8, but absolutely falls apart in KF7:



Side Note: If I am messing with code that must keep very specific whitespace, I typically edit using Calibre's Prettify. 99.9% of the time I prefer Sigil's whitespace cleanup though.
