CSS break-inside Property
The break-inside is a CSS property that defines how any break (page, column) should behave within the generated box. This property is ignored when the generated box is not specified. It has four values: auto, avoid, always, all.
This property is deprecated.
Each element boundary is touched by the three properties below:
- Break-after, which is the value of the previous element.
- Break-before, which is the value of the next element.
- Break inside, which is the value of the containing element.
Apply the rules below, to decide if a break must be done:
- If one of the three values above is a forced break value, it has priority. If one or more of these values is a forced break, the value of the element turned up the latest is used. So, the break-before value has a priority over the break-after value, and the break-after value has a priority over break-inside value.
- If one of these three values is an avoid break value, such a break will not be applied.
