CSS break-before Property
The break-before is a CSS property that defines how any break (page, column) should behave before the generated box. If the generated box is missed, the property is ignored. It has four values: auto, avoid, always, all.
This property is deprecated.
You cannot use the break-after property on absolutely positioned elements or on an <div>.
The page-break-inside, page-break-after, and page-break-before properties help to define how a document must appear when printed.
You should apply the following rules for determining whether or not there must be a break:
- If one of the three related values is a forced break value (left, right, always, column, page, or region), it has a priority. If more than one of these values is forced breaks, the latest element in the flow will be taken.
- If any of the three related values is an avoid break value (avoid, avoid-column, avoid-region, or avoid-page), no such break will be applied.

It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. </p>
