Re: Code validation: bug or what? ;-)

Bernard,

This isn’t the right place to ask. This mailing list is only for announcements from the CSS Working Group, which does not maintain a validator.

I expect that whatever validator you are using does not yet understand nesting. If it’s the Nu validator, you could log an issue for that here: https://github.com/validator/validator/


Thanks,

Alan

Hi guys,

Hope you are well.

Sorry if this is not the place to post this question but I couldn't find
anywhere else to ask.

I'm following an online course on Coursera and I use your tool to
validate HTML and CSS code before submitting tests for course grading.

I have the following css code that doesn't pass validation although all
the documentation I checked on many different sites says the syntax is good.

#link {
   background-color: green;
   padding: 5px;
   text-align: center;
   text-decoration: none;
   position: fixed;
   top: 0;
   left: 50%;
   a {
     color: white;
   }
}

When I try to validate this code for a div selector, the validator lists
an error on line 11. I narrowed it to the a { color: white; } but don't
understand what's wrong. Is it a bug or am I doing something wrong? The
code still shows perfect with the corresponding HTML file on a web page.

Thank you for your time and help.

Regards,

Bernard.
