Avoid serving legacy JavaScript to modern browsers Potential savings of 18 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.

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.

ARIA roles must have valid values in order to perform their intended accessibility functions. Learn more about valid ARIA roles.
Background and foreground colors have a sufficient contrast ratio
Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.

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.

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.
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.

<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.

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.

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.

Best Practices
User Experience
Does not have a <meta name="viewport"> tag with width or initial-scale
No `<meta name="viewport">` tag found
A <meta name="viewport"> not only optimizes your app for mobile screen sizes, but also prevents a 300 millisecond delay to user input. Learn more about using the viewport meta tag.
Document doesn't use legible font sizes
Text is illegible because there's no viewport meta tag optimized for mobile screens.
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. Learn more about legible font sizes.
Browser Compatibility
Page lacks the HTML doctype, thus triggering quirks-mode
Document must contain a doctype
Specifying a doctype prevents the browser from switching to quirks-mode. Learn more about the doctype declaration.

Avoid large layout shifts 2 layout shifts found
These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to windowing. Learn how to improve CLSCLS

For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.

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.

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.
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.

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.
