Valid CSS

Invalid style-declaration found

The inspected CSS file or the CSS rules contained in the inspected (X)HTML file contain invalid CSS rules.

Please check your page and the connected style-sheets with the W3C CSS Validation Service to get detailed information about the errors.

Why this may be a barrier

HTML and CSS documents must follow the rules set in the formal grammar of the language.

Documents created according to published formal grammars are supported by more browsers. Invalid CSS code may lead to a distorted presentation of the content, and make a web page directly inaccessible.
