ARIA `role`s enable assistive technologies to know the role of each element on the web page. If the `role` values are misspelled, not existing ARIA `role` values, or abstract roles, then the purpose of the element will not be communicated to users of assistive technologies. [Learn more about ARIA roles](https://dequeuniversity.com/rules/axe/4.7/aria-allowed-roles).

Values assigned to `role=""` are valid ARIA roles.

ARIA dialog elements without accessible names may prevent screen readers users from discerning the purpose of these elements. [Learn how to make ARIA dialog elements more accessible](https://dequeuniversity.com/rules/axe/4.7/aria-dialog-name).

Elements with `role="dialog"` or `role="alertdialog"` do not have accessible names.

Assistive technologies, like screen readers, work inconsistently when `aria-hidden="true"` is set on the document `<body>`. [Learn how `aria-hidden` affects the document body](https://dequeuniversity.com/rules/axe/4.7/aria-hidden-body).

`[aria-hidden="true"]` is not present on the document `<body>`

Focusable descendents within an `[aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers. [Learn how `aria-hidden` affects focusable elements](https://dequeuniversity.com/rules/axe/4.7/aria-hidden-focus).

`[aria-hidden="true"]` elements do not contain focusable descendents

Some ARIA roles have required attributes that describe the state of the element to screen readers. [Learn more about roles and required attributes](https://dequeuniversity.com/rules/axe/4.7/aria-required-attr).

`[role]`s have all required `[aria-*]` attributes

ARIA roles must have valid values in order to perform their intended accessibility functions. [Learn more about valid ARIA roles](https://dequeuniversity.com/rules/axe/4.7/aria-roles).

`[role]` values are valid

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. [Learn how to make buttons more accessible](https://dequeuniversity.com/rules/axe/4.7/button-name).

Buttons have an accessible name

A character encoding declaration is required. It can be done with a `<meta>` tag in the first 1024 bytes of the HTML or in the Content-Type HTTP response header. [Learn more about declaring the character encoding](https://developer.chrome.com/docs/lighthouse/best-practices/charset/).

Properly defines charset

Low-contrast text is difficult or impossible for many users to read. [Learn how to provide sufficient color contrast](https://dequeuniversity.com/rules/axe/4.7/color-contrast).

Background and foreground colors do not have a sufficient contrast ratio.

Search engines may use `href` attributes on links to crawl websites. Ensure that the `href` attribute of anchor elements links to an appropriate destination, so more pages of the site can be discovered. [Learn how to make links crawlable](https://support.google.com/webmasters/answer/9112205)

hreflang links tell search engines what version of a page they should list in search results for a given language or region. [Learn more about `hreflang`](https://developer.chrome.com/docs/lighthouse/seo/hreflang/).

Document has a valid `hreflang`

If a page doesn't specify a `lang` attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. [Learn more about the `lang` attribute](https://dequeuniversity.com/rules/axe/4.7/html-has-lang).

`<html>` element does not have a `[lang]` attribute

Pages with unsuccessful HTTP status codes may not be indexed properly. [Learn more about HTTP status codes](https://developer.chrome.com/docs/lighthouse/seo/http-status-code/).

All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding [mixed content](https://developers.google.com/web/fundamentals/security/prevent-mixed-content/what-is-mixed-content), where some resources are loaded over HTTP despite the initial request being served over HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. [Learn more about HTTPS](https://developer.chrome.com/docs/lighthouse/pwa/is-on-https/).

`[user-scalable="no"]` is not used in the `<meta name="viewport">` element and the `[maximum-scale]` attribute is not less than 5.

The `unload` event does not fire reliably and listening for it can prevent browser optimizations like the Back-Forward Cache. Use `pagehide` or `visibilitychange` events instead. [Learn more about unload event listeners](https://web.dev/bfcache/#never-use-the-unload-event)

Avoids `unload` event listeners

Users are mistrustful of or confused by sites that request to send notifications without context. Consider tying the request to user gestures instead. [Learn more about responsibly getting permission for notifications](https://developer.chrome.com/docs/lighthouse/best-practices/notification-on-start/).

Avoids requesting the notification permission on page load

Preventing input pasting is a bad practice for the UX, and weakens security by blocking password managers.[Learn more about user-friendly input fields](https://developer.chrome.com/docs/lighthouse/best-practices/paste-preventing-inputs/).
