Thank you so much for looking into this Alison!
This kind of solved my last problem but now, the update has created two different problems (so sorry to keep asking!). The first issue is that my table of contents gets mixed up with the text (see below):

I've seen it be pushed to the left (the Mockup Blog from Thomas Mock is a great example). Is there any way to do this in a Distill Article? Or is it just for websites?
The other issue is that... before installing the GitHub version, I could format the text code (i.e. text that was wrapped in ``) with the following CSS:
/* Tweak code text */
code {
font-family: 'Fira Code', monospace;
color: #224888;
background: #F4F3EE;
font-weight: 400;
font-size: 0.8em;
}
which yielded something like this:

while my code chunks were exempted from such formattings, like so:

But after the update, now my code chunks also follow the above CSS formatting, so my chunks look like:

which is not ideal haha. My question is: is there any way to ONLY format the outside code text? (i.e. text wrapped in `` )?
Once again, thank you so much in advance! Please let me know how I can repay the much-needed help! I could donate to some Patreon account or something!
Best,
Alexis
