+# Dynamically Create HTML Elements
+
+An HTML element can be created with a string that matches a recognized
+entity.
+
+```javascript
+const Paragraph = 'p';
+return <Paragraph>Some paragraph content</Paragraph>
+```
+
+This means we can dynamically create HTML elements such as headers:
+
+```javascript
+const H = ({ level, ...props }) => {
+  const Heading = `h${Math.min(level, 6)}`;
+  return <Heading {...props} />;
+};
+
+return (
+  <React.Fragment>
+    <H level={1}>Header 1</H>
+    <H level={2}>Header 2</H>
+    <H level={5}>Header 5</H>
+  </React.Fragment>
+);
+```
+
+With some

+I've created a [live example here](https://codesandbox.io/s/3v202wmmy1).
