<div id="article">
    <h1 id="intro">Introduction</h1>
<p style="margin-top:0">
    <span class="fake-region-style">This is an example that shows how content
can be made to flow between multiple regions. The image is
displayed in</span> box 'A'. The 'article' is flowed from
region '1', to region '2', to region '3' and finally to region
'4'. Note how the content that is laid out in 'region 1' can be
subject to a different style.
</p>

    <h2 id="more">More Details</h2>
<p>
    This illustrates some of the features of CSS Regions. First,
    the ability to associate a flow of content to a set of
    regions and effectively getting that content to be threaded
    from one region to the next.
</p>
</p>
    Then, the example illustrates the concept of 'region styling',
    where the content that falls into a specific region is subject
    to additional style rule, in the same spirit as inline content
    falling in the 'first line' can be subject to additional styling
    as defined by the ::first-line pseudo element selector.
</p>
<p>
    Finally, this initial example shows that the concept of region
    is orthogonal to the layout of regions. This means that regions
    can be created and positioned using existing CSS and HTML
    layout (such as multi-column, flex box or grid layout).
    The CSS Regions specification defines how these regions can
    be the recipients of a 'named flow'.
