### Why is this important?
When there is more than one toolbar on a page, each must be uniquely labeled to help assistive technology users understand each toolbar’s purpose.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* For each element with a `"toolbar"` role, either set the value of the `aria-labelledby` attribute to the `id` value of any visible text that appropriately and uniquely describes that toolbar's purpose;
* **Or**, use the `aria-label` attribute to add an invisible, unique, non-empty label to an element with the `"toolbar"` role.
The following example shows two containers created with the ARIA `"toolbar"` role. Each container is uniquely labeled with `aria-label` and `aria-labelledby` attributes.
```
<div role="toolbar" aria-label="Simple tools">
...
</div>
<div role="toolbar" aria-labelledby="ct">
<h2 id="ct">Complex tools</h2>
...
</div>
```
</script></mark-down>
<!-- End main panel -->
