   I can confirm, that the parser bails out when parsing the construct (even when not embedded into HTML).
   
   13 is already in the process to being released and only open for release critical fixes, this is not a regression and CSS for print is not the main use-case. Sorry, but this feature won't be supported in 13. If anyone wants to look at this for 14, the right place to start is `ide/css.lib`. The grammar is in the `Css3.g` file in the `org.netbeans.modules.css.lib` package. After changing the grammar, the lexer and parser have to be regenerated (see the `build.xml` of that module for that).
   
   A trivial test is:
   
   ```java
       public void testX() {
           assertParses(" @page {\n" +
   "                @top-center {\n" +
   "                    content: element(top);\n" +
   "                }\n" +
   "                @bottom-center {\n" +
   "                    content: element(bottom);\n" +
   "                }\n" +
   "            }", true);
       }
   ```
