The break-after
CSS property sets how page, column, or region breaks should behave after a generated box. If there is no generated box, the property is ignored.
/* Generic break values */ break-after: auto; break-after: avoid; break-after: always; break-after: all; /* Page break values */ break-after: avoid-page; break-after: page; break-after: left; break-after: right; break-after: recto; break-after: verso; /* Column break values */ break-after: avoid-column; break-after: column; /* Region break values */ break-after: avoid-region; break-after: region; /* Global values */ break-after: inherit; break-after: initial; break-after: 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:
always
, left
, right
, page
, column
, or region
), it has precedence. If more than one of them are such a break, the one of the element that appears the latest in the flow is taken (i.e., the break-before
value has precedence over the break-after
value, which itself has precedence over the break-inside
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.
The break-after
property is specified as one of the keyword values from the list below.
auto
avoid
always
all
avoid-page
page
left
right
recto
verso
avoid-column
column
avoid-region
region
For compatibility reasons, the legacy page-break-after
property should be treated by browsers as an alias of break-after
. This ensures that sites using page-break-after
continue to work as designed. A subset of values should be aliased as follows:
page-break-after | break-after |
---|---|
auto | auto |
left | left |
right | right |
avoid | avoid |
always | page |
The always
value of page-break-*
was implemented by browsers as a page break, and not as a column break. Therefore the aliasing is to page
, rather than the always
value in the Level 4 spec.
Initial value | auto |
---|---|
Applies to | block-level elements |
Inherited | no |
Computed value | as specified |
Animation type | discrete |
auto | avoid | always | all | avoid-page | page | left | right | recto | verso | avoid-column | column | avoid-region | region
In the following example we have a container that contains an <h1>
spanning all columns (achieved using column-span: all
) and a series of <h2>
s and paragraphs laid out in multiple columns using column-width: 200px
.
By default, the subheadings and paragraphs were laid out rather messily because the headings were not in a uniform place. However, we used break-after: column
on the <p>
elements to force a column break after each one, meaning that you end up with an <h2>
neatly at the top of each column.
<article> <h1>Main heading</h1> <h2>Subheading</h2> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla vitae fringilla mauris. Quisque commodo eget nisi sed pretium. Mauris luctus nec lacus in ultricies. Mauris vitae hendrerit arcu, ac scelerisque lacus. Aliquam lobortis in lacus sit amet posuere. Fusce iaculis urna id neque dapibus, eu lacinia lectus dictum.</p> <h2>Subheading</h2> <p>Praesent condimentum dui dui, sit amet rutrum diam tincidunt eu. Cras suscipit porta leo sit amet rutrum. Sed vehicula ornare tincidunt. Curabitur a ipsum ac diam mattis volutpat ac ut elit. Nullam luctus justo non vestibulum gravida. Morbi metus libero, pharetra non porttitor a, molestie nec nisi.</p> <h2>Subheading</h2> <p>Vivamus eleifend metus vitae neque placerat, eget interdum elit mattis. Donec eu vulputate nibh. Ut turpis leo, malesuada quis nisl nec, volutpat egestas tellus. <h2>Subheading</h2> <p>In finibus viverra enim vel suscipit. Quisque consequat velit eu orci malesuada, ut interdum tortor molestie. Proin sed pellentesque augue. Nam risus justo, faucibus non porta a, congue vel massa. Cras luctus lacus nisl, sed tincidunt velit pharetra ac. Duis suscipit faucibus dui sed ultricies.</p> </article>
