Support for column-span

[fabiobatalha]

Is any kind of envisioning to give support for column-span.

Example of use of column-span using the tool PagedJS:

The same PDF file produced with WeasyPrint using the same HTML and CSS's.

Is any kind of envisioning to give support for column-span.

Nothing has been done yet to support column-span, but it would be quite easy to handle simple cases (ie at least without fixed height).

The overall goal is to change the columns_layout function (in layout/columns.py) to split the box at the beginning of the function into multiple boxes. For example:

div {columns: 2}
h2 {column-span: all}

<div>abc def <h2>test</h2> ghi jkl</div>

In this case, we have to:

• go through box (the div element) to find the h2 element,
• render <div>abc def (with the current code) and <h2>test</h2> (with some added code),
• render ghi jkl</div> for example by calling columns_layout with the current skip_stack.

If anyone is interested in implementing this feature, I'll be happy to help!
