CSS Lexical Error

Question

I was having trouble with how an image is displaying and so I ran it through the W3C CSS validator and I received this code. I tried to search around for what it might mean but couldn't find much help. I found some people saying that it might be because of special characters in the CSS so I checked that in notepad ++ and didn't find anything.

2840 #whoweare img

Lexical error at line 2838, column 10. Encountered: " " (32), after : "#" post-9 #whoweare { width:100%; }

# post-9 #whoweare {
    width:100%;
}

Line 2840 is the last one.

Any ideas what this might be?

Thanks for the help.

Answer 1

Remove the space between # and post-9 you have a descendant combinator between them.

#post-9 #whoweare {
   width:100%;
}
