If you re-size the width of the display window, you can see that the headline looks a little funny when only one word is left at the bottom. Designers hate this.
The orphans declaration isn't currently supported unless you're in a paged media, or columns. This is the correct behavior re the CSS spec. But wouldn't it be nice to use it in other contexts?
In this example, it'd be nice if
orphans: 4; on the
h1 meant that the browser re-flowed the text such that 4 was the minimum number of words remaining in the bottom line of the paragraph.
It'd also be nice if
widows were changed similarly.
