To create sidenotes, I use a blockquote floated with a max-width.

When the main, surrounding text is justified, the text renders as overlapping and unreadable, but only when the sidenote runs onto a second page, and only on the page that the note starts on.

When `text-align` is not `justify`, there is no problem.

I'm attaching an HTML file to show this, and a JPG of my result.

I'm using Prince 11 from the CLI on Windows 10.

Are you using Prince 11.2? There was a bug fix for justified text next to floats.

Ha! I was using 11.0. That fixes it. Thank you!
