Examples 3e5p5z
Since only margins, orphans, widows, and page breaks can be styled inside an @page rule, styling any of these for a blank page does not make sense.
However, in CSS3, at-rules that select and target page margins were introduced. They have no browser at this time. But the following is an example of how you might style an empty page using a page margin at-rule; the example inserts content into the center of the top margin of an empty page:
@page :blank {
@top-center { content: "This page is intentionally left blank" }
}
More information about this will be provided once available.
