+# Make Elements Non-Interactive With Inert
+
+The [`inert`
+attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/inert)
+global attribute is a boolean that can be applied to an element or section of
+content in an HTML document. When it is `true`, that elements and anything
+nested within it will not be interactive.
+
+```html
+<div class="fancy-animation" inert>
+  <!-- ... -->
+</div>
+```
+
+This has a couple different implications:
+
+1. Click events are not fired on these elements.
+
+2. These elements will not be able to gain focus.
+
+3. These elements and content are hidden from assistive technology.
+
+This is useful for a variety of things. In particular, it is good for
+accessibility when a portion of the document, like a fancy animation, isn't
+meant to be traversed by assistive technology.
