How to create a pagebreak using HTML Renderer with the latest beta version

Question

When a page break is needed I have included

strPDF += "<div style='page-break-inside: auto;'></div>";

I also tried using

 strPDF += "<p style='page-break-inside: always;'></p>";

but this seems not to work.
Here I am using these
