| ## Implementation | ||
|
|
||
| Both thumbs have a `role` of `slider`, which needs an accessible label. By default, they use a localized version of "min" and "max". | ||
| You can change the labels by setting the `aria-start-label` and `aria-end-label` attributes. | ||
|
|
||
| Vivid automatically sets the `aria-valuetext` attribute on the thumbs. The attribute is read by assistive technology. You can control its format using the `valueTextFormatter` property for a more human-readable value. | ||
