My take

[romu70]

Fixed.

We can also think about having a soft color background instead of the gray, or having a color accent.

[fmartingr]

I would use something simple, a box with a bit darker/lighter background depending on the theme, the text in italics and probably nothing else, to match the simplicity of the rest of the themes.

Once we start working on custom css users could customize this to their needs.

@fmartingr any other change?

Honestly I would be much more simple than that, I don't like extra distractions on transformations on the readable version.

blockquote {
	padding: 15px;
	margin: 15px;
	font-style: italic;
	background: var(--bgqoute);
}

Also I would put this style under the #content section, so it only applies to the readable version.

done
it is better to separate other page like content page CSS to a separate file too like archive.less
