pages collection
Represents a collection of all @page at-rules in a styleSheet object.
The rules in the collection are sorted in source code order.
Although the pages collection is supported, but the @page at-rule does not work in Internet Explorer before version 8.
Note: Page selectors are not supported in Internet Explorer.
If a @page at-rule contains a selector, the rule is parsed as an unknown rule in Internet Explorer from version 8, so it does not get into the pages collection.
In older versions, the pages collection contains all @page at-rules (but they do not work).
In Firefox, Opera, Google Chrome, Safari and Internet Explorer from version 9, use the cssRules collection to get the style rules and at-rules of a style sheet.
