<p>How can the article above be represented? The essential components are:
<ul>
<li>a grid-based layout with 8 columns
<li>a heading that spans all 8 colums
<li>an image that span the right-most 4 colums, all the way to the page edge
<li>in introdutcion that spans the left-most 4 column
</ul>
<p>We will disregard these components:
<ul>
<li>header and footers
<li>the fact that the article stretches across two pages
</ul>

vertical floating within the containing block.

<tr><td>#25 In a multicolumn layout, float an image to the upper right corner of the multicolumn element, spanning two columns, setting the width of the image to be the width of both column boxes and the gap between them. Further, the image has a caption that should be displayed to the right of the image (i.e., outside of the content box of the multicol element). The top of the caption should be aligned with the top of the image.

<tr><td>#28 In a multi-column layout, float an element (containing, say, a quote) to the second column, placing it 10em from the top of the column. The element should fill the width of the column.

<tr><td>#30 In a multi-column layout, float an element (containing, say, a quote) between the first and second column so that the element intrudes into the two neighboring columns. Horizontally, the element should be centered wrt the column gap which is 1em. Vertically, the quote should be in the middle.

<tr><td>#31 In a four-column layout, the outside column should not have any normal content. Instead, images present in the content should be floated to this column, stacked underneath each other in the order they appear. This use case can also be thought of as a three-column layout with an outside margin equal to the width of one column, into which the images are floated.
