<oXygen/> provides special support for developing CSS stylesheet documents.
<oXygen/> includes a built-in CSS validator integrated with the general validation support. This brings the usual validation features to CSS stylesheets.
A content completion assistant similar to the one of XML documents offers the CSS properties and the values available for each property. It is activated on the CTRL + Space shortcut and it is context sensitive when it is invoked for the value of a property.
In a large CSS stylesheet document some styles may be collapsed so that only the needed styles remain in focus. The same folding features available for XML documents are also available in CSS stylesheets.
If the edited CSS stylesheet becomes unreadable because of the bad alignment of the text lines the pretty-print operation available for XML documents is also available for CSS stylesheets. It works in the same way as for XML documents and is available as the same menu and toolbar action.
The CSS editor type offers a reduced version of the popup menu available in the XML editor type, that means only the folding actions, the edit actions and a part of the source actions (only the actions To lower case, To upper case, Capitalize lines).
