Background and foreground colors do not have a sufficient contrast ratio. ( 0 / 100 )
Low-contrast text is difficult or impossible for many users to read.
Image elements do not have `[alt]` attributes ( 0 / 100 )
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute.
Links do not have a discernible name ( 0 / 100 )
Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users.
List items (`<li>`) are not contained within `<ul>` or `<ol>` parent elements. ( 0 / 100 )
Screen readers require list items (`<li>`) to be contained within a parent `<ul>` or `<ol>` to be announced properly.
Some elements have a `[tabindex]` value greater than 0 ( 0 / 100 )
A value greater than 0 implies an explicit navigation ordering. Although technically valid, this often creates frustrating experiences for users who rely on assistive technologies.
`[accesskey]` values are unique ( 100 / 100 )
Access keys let users quickly focus a part of the page. For proper navigation, each access key must be unique.
`[aria-*]` attributes match their roles
Each ARIA `role` supports a specific subset of `aria-*` attributes. Mismatching these invalidates the `aria-*` attributes.
`[aria-hidden="true"]` is not present on the document `<body>` ( 100 / 100 )
Assistive technologies, like screen readers, work inconsistently when `aria-hidden="true"` is set on the document `<body>`.
`[aria-hidden="true"]` elements do not contain focusable descendents ( 100 / 100 )
Focusable descendents within an `[aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers.
ARIA input fields have accessible names
When an input field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[role]`s have all required `[aria-*]` attributes ( 100 / 100 )
Some ARIA roles have required attributes that describe the state of the element to screen readers.
Elements with an ARIA `[role]` that require children to contain a specific `[role]` have all required children. ( 100 / 100 )
Some ARIA parent roles must contain specific child roles to perform their intended accessibility functions.
`[role]`s are contained by their required parent element ( 100 / 100 )
Some ARIA child roles must be contained by specific parent roles to properly perform their intended accessibility functions.
`[role]` values are valid ( 100 / 100 )
ARIA roles must have valid values in order to perform their intended accessibility functions.
ARIA toggle fields have accessible names
When a toggle field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[aria-*]` attributes have valid values
Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid values.
`[aria-*]` attributes are valid and not misspelled
Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid names.
Buttons have an accessible name
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.
The page contains a heading, skip link, or landmark region ( 100 / 100 )
Adding ways to bypass repetitive content lets keyboard users navigate the page more efficiently.
`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements. ( 100 / 100 )
When definition lists are not properly marked up, screen readers may produce confusing or inaccurate output.
Definition list items are wrapped in `<dl>` elements ( 100 / 100 )
Definition list items (`<dt>` and `<dd>`) must be wrapped in a parent `<dl>` element to ensure that screen readers can properly announce them.
Document has a `<title>` element ( 100 / 100 )
The title gives screen reader users an overview of the page, and search engine users rely on it heavily to determine if a page is relevant to their search.
`[id]` attributes on active, focusable elements are unique
All focusable elements must have a unique `id` to ensure that they're visible to assistive technologies.
ARIA IDs are unique ( 100 / 100 )
The value of an ARIA ID must be unique to prevent other instances from being overlooked by assistive technologies.
No form fields have multiple labels
Form fields with multiple labels can be confusingly announced by assistive technologies like screen readers which use either the first, the last, or all of the labels.
`<frame>` or `<iframe>` elements have a title
Screen reader users rely on frame titles to describe the contents of frames.
Heading elements appear in a sequentially-descending order ( 100 / 100 )
Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies.
`<html>` element has a `[lang]` attribute ( 100 / 100 )
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.
`<html>` element has a valid value for its `[lang]` attribute ( 100 / 100 )
Specifying a valid [BCP 47 language](https://www.w3.org/International/questions/qa-choosing-language-tags#question) helps screen readers announce text properly.
`<input type="image">` elements have `[alt]` text
When an image is being used as an `<input>` button, providing alternative text can help screen reader users understand the purpose of the button.
Form elements have associated labels ( 100 / 100 )
Labels ensure that form controls are announced properly by assistive technologies, like screen readers.
Presentational `<table>` elements avoid using `<th>`, `<caption>` or the `[summary]` attribute.
A table being used for layout purposes should not include data elements, such as the th or caption elements or the summary attribute, because this can create a confusing experience for screen reader users.
Lists contain only `<li>` elements and script supporting elements (`<script>` and `<template>`). ( 100 / 100 )
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output.
The document does not use `<meta http-equiv="refresh">`
Users do not expect a page to refresh automatically, and doing so will move focus back to the top of the page. This may create a frustrating or confusing experience.
`[user-scalable="no"]` is not used in the `<meta name="viewport">` element and the `[maximum-scale]` attribute is not less than 5. ( 100 / 100 )
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page.
`<object>` elements have `[alt]` text
Screen readers cannot translate non-text content. Adding alt text to `<object>` elements helps screen readers convey meaning to users.
Cells in a `<table>` element that use the `[headers]` attribute refer to table cells within the same table.
Screen readers have features to make navigating tables easier. Ensuring `<td>` cells using the `[headers]` attribute only refer to other cells in the same table may improve the experience for screen reader users.
`<th>` elements and elements with `[role="columnheader"/"rowheader"]` have data cells they describe.
Screen readers have features to make navigating tables easier. Ensuring table headers always refer to some set of cells may improve the experience for screen reader users.
`[lang]` attributes have a valid value
Specifying a valid [BCP 47 language](https://www.w3.org/International/questions/qa-choosing-language-tags#question) on elements helps ensure that text is pronounced correctly by a screen reader.
`<video>` elements contain a `<track>` element with `[kind="captions"]`
When a video provides a caption it is easier for deaf and hearing impaired users to access its information.
`<video>` elements contain a `<track>` element with `[kind="description"]`
Audio descriptions provide relevant information for videos that dialogue cannot, such as facial expressions and scenes.
The page has a logical tab order
Tabbing through the page follows the visual layout. Users cannot focus elements that are offscreen.
Interactive controls are keyboard focusable
Custom interactive controls are keyboard focusable and display a focus indicator.
Interactive elements indicate their purpose and state
Interactive elements, such as links and buttons, should indicate their state and be distinguishable from non-interactive elements.
The user's focus is directed to new content added to the page
If new content, such as a dialog, is added to the page, the user's focus is directed to it.
User focus is not accidentally trapped in a region
A user can tab into and out of any control or region without accidentally trapping their focus.
Custom controls have associated labels
Custom interactive controls have associated labels, provided by aria-label or aria-labelledby.
Custom controls have ARIA roles
Custom interactive controls have appropriate ARIA roles.
Visual order on the page follows DOM order
DOM order matches the visual order, improving navigation for assistive technology.
Offscreen content is hidden from assistive technology
Offscreen content is hidden with display: none or aria-hidden=true.
HTML5 landmark elements are used to improve navigation
Landmark elements (<main>, <nav>, etc.) are used to improve the keyboard navigation of the page for assistive technology.

Links are not crawlable ( 0 / 100 )
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 More](https://support.google.com/webmasters/answer/9112205)
Image elements do not have `[alt]` attributes ( 0 / 100 )
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute.
Document doesn't use legible font sizes ( 0 / 100 )
Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px.
| 3.43% legible text |
Tap targets are not sized appropriately ( 62 / 100 )
