This page contains various use cases to support the analysis and discussion about what we should do with page, column and regions breaks.
Separate each section designated by a heading element on a distinct region.
<div id="r1" style="content:from-flow(article)"></div> <div id="r2" style="content:from-flow(article)"></div> <div id="r3" style="content:from-flow(article)"></div> <div style="flow:article"> <h2 style="break-before: region"></h2> <p>...</p> <h2 style="break-before: region"></h2> <p>...</p> <h2 style="break-before: region"></h2> <p>...</p> </div>
<div style="columns:3"> <p id="p_0">...</p> <p id="p_1" style="break-before:page">...</p> <p id="p_2" style="break-after:column">...</p> <p id="p_3">...</p> </div>
In this use case, the break-before on p_1 indicates that the page flow should be broken. The <div> is part of the page flow and is broken, causing a new row to be created for the multi-column element (3 new columns). So p_2 will find itself on the second page. Because there is a break-after:column on p_2, p_3 will be laid out at the beginning of the second column, on the second page.
<div id="r0" style="content:from-flow(article)"> </div> <div id="r1" style="content:from-flow(article)"> </div> <div id="r2" style="content:from-flow(article)"> </div> <div style="flow:article"> <p id="p_0">...</p> <p id="p_1" style="break-before:page">...</p> <p id="p_2" style="break-after:region">...</p> <p id="p_3">...</p> </div>
<div id="d1" style="columns:3"> <div id="d_11">...</div> <div id="d_12" style="columns:3"> <p id="p_0">...</p> <p id="p_1">...</p> <p id="p_2" style="break-after:column">...</p> <p id="p_3">...</p> </div> <div id="d_13" style="break-before: column">...</div> </div>
Avoid breaking ordered lists. The index needs to be incrementally correct.
<div id="r1" style="content:from-flow(article)"></div> <div id="r2" style="content:from-flow(article)"></div> <div style="flow:article"> <p>...</p> <ol style="break-before: region">...</ol> <p>...</p> </div>
<div id="r1" style="content:from-flow(article)"></div> <div id="r2" style="content:from-flow(article)"></div> <div style="flow:article"> <p>...</p> <table style="break-before: region">...</table> <p>...</p> </div>
Allow breaking of nested lists, ordered or unordered, across regions. Keep the correct nesting index and indentation across regions.
