FireFox error "Selector expected. Ruleset ignored due to bad selector"
18 comments. Current rating:

Question:
The javascript-console of FireFox gives me these errors:Error: Selector expected. Ruleset ignored due to bad selector.
followed by
Error: Unexpected end of file while searching for closing } of invalid rule set.
Do you have any ideas on what this means and how to resolve it?
Answer:
Review your .CSS style sheet file. You probably have HTML comments in there, similar to what people put in Javascript sections. Remove those comments as shown below. |  | |
// this will cause an error in Firefox: <style> <!-- .styling { blah... } //--> </style> // this is ok: <style> .styling { blah... } </style> | ||

Where's the .CSS style sheet file located?
| ||
| ||

I get that warning, but dont have any //-> in my style sheet (
 http://www.bandsman..style.css) | ||

To anonymous in United Kingdom:
I looked at your CSS file. If it is an external .css file, you should not include the <style> and </style> lines. | ||
| ||
|
Hey that worked. Thanks.
| ||
| ||
|
When you are put an semicolon after the } in the styles(like this
.stylename{ width:10% }; ) at that time also this error will come. Just remove the semicolon then it will works use this( .stylename{ width:10% } ) | ||
| ||
|
You may also have something like this in your CSS:
.whatever, { ... } The extra comma shouldn't be there, so just remove it: .whatever { ... } | ||

I actually got this error because I named one of my classes starting with a number:
<style type='text/css' > .100Percent { width: 100%; } </style> When I changed it to the following the error went away: <style type='text/css' > .OneHundredPercent { width: 100%; } </style> | ||

no html tags in an external, right, and check to make sure all the files are in the same directory.... sounds easy nuff, but a common error. least for me...
| ||
| ||
that helped me out thanks I was flummoxed for a while ;o) | ||
| ||
|
I found the error in
BODY, P, {font-family: verdana, arial, sans-serif; font-size: 12pt; color: #000000; text-align: left; } It was the extra comma after P, due to the fact that I deleted another specifier without removing the comma too. | ||

Removing all HTML tags in my CSS file worked for me! Thanks so much!
