I have added the following rule in my CSS file:

.wpb-content-wrapper:has(.firmaPost) {
	width: 100%;
	max-width: 600px;
}

The first line gets highlighted in red and this error is detected by DW:

Exptected RPAREN at line...

However, according to W3 Schools, the syntax is correct.

Why is the error shown?

It's a bug, and it has been ignored for years by Adobe.

In external stylesheets, all kinds of more advanced CSS methods are flagged by DW as errors, within a <style> tagset, inside an html page though, it's not. That's probably why Nancy wasn't able to reproduce it. It immediately shows as an error in a .css file for me and DW's perfectly content with it in an html page.

When in doubt, use the css validator here: https://jigsaw.w3.org/css-validator/

With DW being moved out of active development in 2020-21, the liklihood they'll ever fix it is very low.
