### Why is this important?
Associating a meaningful label with every UI control allows the browser and assistive technology to expose and announce the control to a user.
Associating a visible label also provides a larger clickable area.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If the control is a [labelable](https://html.spec.whatwg.org/multipage/forms.html#category-label) element, add a `for` attribute to a visible label with the `id` of this control (e.g., `<label for="controlID">`)
* **Or**, if the control is a labelable element, put the control inside a visible `<label>` element
* **Or**, add an `aria-labelledby` attribute to the control. It must point to visible text on the page that is meaningful as a label
* **Or**, if the design cannot have a visible label, provide a label using the `aria-label` attribute (e.g., `aria-label="Activities"`)
* **Or**, if the design cannot have a visible label, use the `title` attribute to provide a label
