Are css errors affecting search results?

Question

Google

I checked the sites and noticed that on every site there are css errors. Here is an example of these errors jigsaw.w3.org/css-validator/validator?uri=http%3A%...
Tell me, who understands this, such css errors greatly affect search results, the attitude of robots to the site, etc. d.? And where to find a person who is well versed in css code? There are still other errors showing in the site code. Are these errors critical, is it worth fighting with them, because sites already work fine even with these errors.

Answer 1

Affects Yandex (indirectly) - if errors lead to inconvenience in displaying information or using the site.
For Google - if the site is not adapted for mobile issuance.

Answer 2

No, they do not, and if they do, then only if the site suffers from this (displays incorrectly, etc.) - this is as clear as day, logical.

Answer 3

Forget those validation tools. They are only needed so that you have the right culture of writing code.
Otherwise, errors in CSS do not affect the output, unless, for some reason, the block with the desired text will be invisible on the page. Search engines don't like it.

Answer 4

If they affect the issuance, it is so insignificant that it can be neglected.
The main impact here is on display in different browsers. Some of them will eat an error, some will give a jamb.
