[aria-*] attributes match their roles
Each ARIA role supports a specific subset of aria-* attributes. Mismatching these invalidates the aria-* attributes. Learn how to match ARIA attributes to their roles.
[aria-hidden="true"] is not present on the document <body>
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.
[role]s have all required [aria-*] attributes
Some ARIA roles have required attributes that describe the state of the element to screen readers. Learn more about roles and required attributes.
[aria-*] attributes have valid values
Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid values. Learn more about valid values for ARIA attributes.
[aria-*] attributes are valid and not misspelled
Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid names. Learn more about valid ARIA attributes.
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. Learn how to make buttons more accessible.
Image elements have [alt] attributes
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the alt attribute.
[user-scalable="no"] is not used in the <meta name="viewport"> element and the [maximum-scale] attribute is not less than 5.
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more about the viewport meta tag.
ARIA attributes are used as specified for the element's role
Some ARIA attributes are only allowed on an element under certain conditions. Learn more about conditional ARIA attributes.
Elements with role="dialog" or role="alertdialog" have accessible names.
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.
[aria-hidden="true"] elements do not contain focusable descendents
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.
Elements use only permitted ARIA attributes
Using ARIA attributes in roles where they are prohibited can mean that important information is not communicated to users of assistive technologies. Learn more about prohibited ARIA roles.
[role] values are valid
ARIA roles must have valid values in order to perform their intended accessibility functions. Learn more about valid ARIA roles.
Document has a <title> element
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. Learn more about document titles.
<html> element has a [lang] attribute
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.
<html> element has a valid value for its [lang] attribute
Specifying a valid BCP 47 language helps screen readers announce text properly. Learn how to use the lang attribute.
No element has a [tabindex] value greater than 0
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. Learn more about the tabindex attribute.
Touch targets have sufficient size and spacing.
Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.
Heading elements appear in a sequentially-descending order
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. Learn more about heading order.
Uses ARIA roles only on compatible elements
Many HTML elements can only be assigned certain ARIA roles. Using ARIA roles where they are not allowed can interfere with the accessibility of the web page. Learn more about ARIA roles.
Deprecated ARIA roles were not used
Deprecated ARIA roles may not be processed correctly by assistive technology. Learn more about deprecated ARIA roles.
Image elements do not have [alt] attributes that are redundant text.
Informative elements should aim for short, descriptive alternative text. Alternative text that is exactly the same as the text adjacent to the link or image is potentially confusing for screen reader users, because the text will be read twice. Learn more about the alt attribute.

Screen reader users rely on frame titles to describe the contents of frames. Learn more about frame titles.
<html> element has an [xml:lang] attribute with the same base language as the [lang] attribute.
If the webpage does not specify a consistent language, then the screen reader might not announce the page's text correctly. Learn more about the lang attribute.
Input buttons have discernible text.
Adding discernable and accessible text to input buttons may help screen reader users understand the purpose of the input button. Learn more about input buttons.
<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. Learn about input image alt text.
Form elements have associated labels
Labels ensure that form controls are announced properly by assistive technologies, like screen readers. Learn more about form element labels.
Lists contain only <li> elements and script supporting elements (<script> and <template>).
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more about proper list structure.
List items (<li>) are contained within <ul>, <ol> or <menu> parent elements
Screen readers require list items (<li>) to be contained within a parent <ul>, <ol> or <menu> to be announced properly. Learn more about proper list structure.
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. Learn more about the refresh meta tag.
<object> elements have alternate text
Screen readers cannot translate non-text content. Adding alternate text to <object> elements helps screen readers convey meaning to users. Learn more about alt text for object elements.
Select elements have associated label elements.
Form elements without effective labels can create frustrating experiences for screen reader users. Learn more about the select element.
Tables have different content in the summary attribute and <caption>.
The summary attribute should describe the table structure, while <caption> should have the onscreen title. Accurate table mark-up helps users of screen readers. Learn more about summary and caption.
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. Learn more about the headers attribute.
<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. Learn more about table headers.
[lang] attributes have a valid value
Specifying a valid BCP 47 language on elements helps ensure that text is pronounced correctly by a screen reader. Learn how to use the lang attribute.
<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. Learn more about video captions.

Uses HTTPS
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding 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.
