Summary

The break-after CSS property describes the page, column, or region break behavior (in other words, how and whether to break) after the generated box. If there is no generated box, the property is ignored.

Each possible break point (in other words, each element boundary) is affected by three properties: the break-after value of the previous element, the break-before value of the next element and the break-inside of the containing element.

To define if a break must be done, the following rules are applied:

  1. If any of the three concerned values is a forced break value, that is always, left, right, page, column or region, it has precedence. If several of the concerned values is such a break, the one of the element that appears the latest in the flow is taken (that is the break-before value has precedence over the break-after value, which itself has precedence over the break-inside value).
  2. If any of the three concerned values is an avoid break value, that is avoid, avoid-page, avoid-region, avoid-column, no such break will be applied at that point.

Once forced breaks have been applied, soft breaks may be added if needed, but not on element boundaries that resolve in a corresponding avoid value.
