Yes. A margin-top was added to ul and ol elements. I fixed it with the following CSS:

.memo_markdown_styles_markdown-class ul, 
.memo_markdown_styles_markdown-class ol {
    margin: 0;
    line-height: 2;
}

I also added a `line-height`, as I think the default is too cramped.
It appears you're using my everforest theme. I'll wait for Matt's reply before applying the fix to the theme.

Yes. I'm using your theme. I love it. So, I have to add a margin-top as you did to fix it, is that correct?

Yes, correct. I pushed an update to the theme anyway. Just download the new file from GitHub :)

Thank you, Sayed.
