break-inside

The break-inside CSS property defines how page, column, or region breaks should behave inside a generated box. If there is no generated box, the property is ignored.

/* Keyword values */
break-inside: auto;
break-inside: avoid;
break-inside: avoid-page;
break-inside: avoid-column;
break-inside: avoid-region;

/* Global values */
break-inside: inherit;
break-inside: initial;
break-inside: unset;

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 value of the containing element.

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

1. If any of the three concerned values is a forced break value (always, left, right, page, column, or region), it has precedence. If more than one of them are such a break, the value of the element that appears the latest in the flow is used. Thus, the break-before value has precedence over the break-after value, which in turn has precedence over the break-inside value.
2. If any of the three concerned values is an avoid break value (avoid, avoid-page, avoid-region, or 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.
