 ## Accessibility
 
+### Screen Readers
+
+Action Sheets set aria properties in order to be [accessible](../reference/glossary#a11y) to screen readers, but these properties can be overridden if they aren't descriptive enough or don't align with how the action sheet is being used in an app.
+
+#### Role
+
 Action Sheets are given a `role` of [`dialog`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/dialog_role). In order to align with the ARIA spec, either the `aria-label` or `aria-labelledby` attribute must be set.
 
+#### Action Sheet Description
+
 It is strongly recommended that every Action Sheet have the `header` property defined, as Ionic will automatically set `aria-labelledby` to point to the header element. However, if you choose not to include a `header`, an alternative is to use the `htmlAttributes` property to provide a descriptive `aria-label` or set a custom `aria-labelledby` value.

 ## Accessibility
 
+### Screen Readers
+
+Alerts set aria properties in order to be [accessible](../reference/glossary#a11y) to screen readers, but these properties can be overridden if they aren't descriptive enough or don't align with how the alert is being used in an app.
+
+#### Role
+
 Ionic automatically sets the Alert's `role` to either [`alertdialog`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/alertdialog_role) if there are any inputs or buttons included, or [`alert`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/alert_role) if there are none.
 
+#### Alert Description
+
 If the `header` property is defined for the Alert, the `aria-labelledby` attribute will be automatically set to the header's ID. The `subHeader` element will be used as a fallback if `header` is not defined. Similarly, the `aria-describedby` attribute will be automatically set to the ID of the `message` element if that property is defined.
 
 It is strongly recommended that your Alert have a `message`, as well as either a `header` or `subHeader`, in order to align with the ARIA spec. If you choose not to include a `header` or `subHeader`, an alternative is to provide a descriptive `aria-label` using the `htmlAttributes` property.
