+
+There is an [HTML
+tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/sup) that
+tells browser engines to render text as superscript -- like when you need an
+exponent.
+
+```
+<p>Render this text as <sup>superscript</sup>!</p>
+```

+
+<p>Render this text as <sup>superscript</sup>!</p>
