For finer tuning of your PDF, you can try to force page breaks or avoid them. The renderer will try to follow your settings, but it's not always possible to avoid or force a break in the spot you desire.
page-break-before , page-break-after , page-break-inside let you provide suggestions to the render, with CSS like this:
.chapter { page-break-before: always; }
.heading { page-break-after: avoid; }
section { page-break-inside: avoid; }These properties can be applied to block-level elements, table rows and table row groups.
page-break-inside only accepts avoid as a value, but page-break-before and page-break-after also accept always as a value. The default value is auto for all three properties.
