Avoid serving legacy JavaScript to modern browsers
0.15 s
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.

These checks highlight opportunities to improve the accessibility of your web app. Only a subset of accessibility issues can be automatically detected so manual testing is also encouraged.
NavigationThese are opportunities to improve keyboard navigation in your application.
[accesskey] values are unique Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Access keys let users quickly focus a part of the page. For proper navigation, each access key must be unique. Learn more.

Names and labelsThese are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Buttons have an accessible name Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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 more.
Document has a <title> element Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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.
No form fields have multiple labels Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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 more.
<frame> or <iframe> elements have a title Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Screen reader users rely on frame titles to describe the contents of frames. Learn more.
Image elements have [alt] attributes Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more.
<input type="image"> elements have [alt] text Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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 more.

Labels ensure that form controls are announced properly by assistive technologies, like screen readers. Learn more.
<object> elements have [alt] text Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Screen readers cannot translate non-text content. Adding alt text to `<object>` elements helps screen readers convey meaning to users. Learn more.
ContrastThese are opportunities to improve the legibility of your content.
Background and foreground colors have a sufficient contrast ratio Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Low-contrast text is difficult or impossible for many users to read. Learn more.
Tables and listsThese are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.
<dl>'s contain only properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements. Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
When definition lists are not properly marked up, screen readers may produce confusing or inaccurate output. Learn more.
Definition list items are wrapped in <dl> elements Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Definition list items (`<dt>` and `<dd>`) must be wrapped in a parent `<dl>` element to ensure that screen readers can properly announce them. Learn more.
Presentational <table> elements avoid using <th>, <caption> or the [summary] attribute. Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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. Learn more.
Lists contain only <li> elements and script supporting elements (<script> and <template>). Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more.
List items (<li>) are contained within <ul> or <ol> parent elements Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
Screen readers require list items (`<li>`) to be contained within a parent `<ul>` or `<ol>` to be announced properly. Learn more.
Cells in a <table> element that use the [headers] attribute refer to table cells within the same table. Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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.
<th> elements and elements with [role="columnheader"/"rowheader"] have data cells they describe. Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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.
Internationalization and localizationThese are opportunities to improve the interpretation of your content by users in different locales.
<html> element has a [lang] attribute Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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.
<html> element has a valid value for its [lang] attribute Error!

Best practicesThese items highlight common accessibility best practices.
The document does not use <meta http-equiv="refresh"> Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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.
[user-scalable="no"] is not used in the <meta name="viewport"> element and the [maximum-scale] attribute is not less than 5. Error!
Required Accessibility gatherer encountered an error: PROTOCOL_TIMEOUT
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.
