I am reading a codebase and trying to replicate it part by part. However I am getting a css parsing error for the following css line:
#pp:not([class*="pelwqu"]) #s199 {
background-image: url("https://bgnmypdu.helldomain.oy.ne.ro");
}
Additionally, I did not get the components of this line. Can you explain which part is needed for what and why? Thank you.
