Elements with the role=text attribute do not have focusable descendents.
Adding role=text around a text node split by markup enables VoiceOver to treat it as one phrase, but the element's focusable descendents will not be announced. Learn more about the role=text attribute.
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. Learn more about toggle fields.
ARIA tooltip elements have accessible names
When a tooltip element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers. Learn how to name tooltip elements.
ARIA treeitem elements have accessible names
When a treeitem element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers. Learn more about labeling treeitem elements.

Adding ways to bypass repetitive content lets keyboard users navigate the page more efficiently. Learn more about bypass blocks.
<dl>'s contain only properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements.
When definition lists are not properly marked up, screen readers may produce confusing or inaccurate output. Learn how to structure definition lists correctly.
Definition list items are wrapped in <dl> elements
Definition list items (<dt> and <dd>) must be wrapped in a parent <dl> element to ensure that screen readers can properly announce them. Learn how to structure definition lists correctly.
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. Learn how to use form labels.
<frame> or <iframe> elements have a title
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.
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.

<frame> or <iframe> elements have a title
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.
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.
