Validating CSS Stylesheets

Oxygen XML Author plugin includes a built-in CSS Validator, integrated with general validation support. This makes the usual validation features for presenting errors also available for CSS stylesheets.

The CSS properties accepted by the validator are those included in the current CSS profile that is selected in the CSS validation preferences. The CSS 3 with Oxygen extensions profile includes all the CSS 3 standard properties plus the CSS extensions specific for Oxygen that can be used in Author mode. That means all Oxygen specific extensions are accepted in a CSS stylesheet by the built-in CSS validator when this profile is selected.
