      In this example, <code>polygon()</code> is being used in the <code>shape-outside</code> property to "trace" around the illustration of the sleeping red panda. This allows text to flow around it. Try commenting out the <code>shape-outside</code> property in this Pen's CSS to see how the text wrapping changes, or using <a href="https://developer.mozilla.org/en-US/docs/Tools/Page_Inspector/How_to/Edit_CSS_shapes">Firefox's Shape Path Editor</a> tool to edit the polygon shape.

        The red panda (<i>Ailurus fulgens</i>) is a mammal native to the eastern Himalayas and southwestern China.
        alt="A cartoon red panda sleeping on a log."
        The red panda has reddish-brown fur, a long, shaggy tail, and a waddling gait due to its shorter front legs; it is roughly the size of a domestic cat, though with a longer body and somewhat heavier. It is arboreal, feeds mainly on bamboo, but also eats eggs, birds, and insects. It is a solitary animal, mainly active from dusk to dawn, and is largely sedentary during the day. It is also called the <b>lesser panda</b>, the <b>red bear-cat</b>, and the <b>red cat-bear</b>.
        The red panda is the only living species of the genus Ailurus and the family <i>Ailuridae</i>. It has been previously placed in the raccoon and bear families, but the results of phylogenetic analysis provide strong support for its taxonomic classification in its own family, <i>Ailuridae</i>, which is part of the superfamily <i>Musteloidea</i>, along with the weasel, raccoon and skunk families. Two subspecies are recognized. It is not closely related to the giant panda, which is a <i>basal ursid</i>.
