Accessibility

Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of cn.com. This includes details about various page attributes that can be optimized.

Navigation

`[accesskey]` values are unique
Access keys assist users with focusing on different parts of the page. Each access key should be unique for proper navigation.

The page contains a heading, skip link, or landmark region
It is advised to provide ways to bypass repetitive content, allowing users to navigate the page efficiently.

`[id]` attributes on active, focusable elements are unique
Ensure all focusable elements have a unique id value to allow them to be visible to users of assistive technologies, like a screen reader.

Heading elements appear in a sequentially-descending order
Properly order all headers and do not skip heading levels to better the navigation and readability for users of assistive technologies, like a screen reader.

No element has a `[tabindex]` value greater than 0
Although technically valid, a tabindex value greater than 0 often creates frustrating experiences for users who rely on assistive technologies.

ARIA

`[aria-*]` attributes match their roles
Avoid mismatching 'aria-*' attributes and their 'role' value, as it invalidates the attribute.

`[aria-hidden="true"]` is not present on the document `<body>`
If aria-hidden=true is set on the document body, assistive technologies, like a screen reader will work inconsistently.

`[aria-hidden="true"]` elements do not contain focusable descendents
Interactive elements within an aria-hidden=true element are unavailable to users of assistive technologies, like a screen reader.

ARIA input fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when an input field does not have an accessible name specified.

`[role]`s have all required `[aria-*]` attributes
Some ARIA roles have required 'aria-*' attributes, which provide essential information about state and functionality.

Elements with an ARIA `[role]` that require children to contain a specific `[role]` have all required children.
Some ARIA parent roles cannot perform their intended functions if specific child roles are not used.

`[role]`s are contained by their required parent element
Some ARIA child roles cannot perform their intended functions if specific parent roles are not used.

`[role]` values are valid
All ARIA roles require valid values to perform their intended functions.

ARIA toggle fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when a toggle field does not have an accessible name specified.

`[aria-*]` attributes have valid values
ARIA attributes cannot be interpreted with invalid values when used by screen readers and other assistive technologies.

`[aria-*]` attributes are valid and not misspelled
ARIA attributes cannot be interpreted with invalid names when used by screen readers and other assistive technologies.

ARIA IDs are unique
Ensure all ARIA ID values are unique to prevent elements from being overlooked by assistive technologies, like a screen reader.

Names and labels

Buttons have an accessible name
Buttons become unusable as they are announced simply as "button" when the button does not have an accessible name, when used by screen readers and other assistive technologies.

Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.

No form fields have multiple labels
Having multiple labels for form fields can be confusing to assistive technologies, like a screen reader.

`<frame>` or `<iframe>` elements have a title
Screen reader users and other assistive technology users rely on frame titles to describe the contents of frames.

`<input type="image">` elements have `[alt]` text
Input buttons with alternative text assist screen readers and other assistive technology users to understand its purpose.

`<object>` elements have `[alt]` text
It is advised that alt text is used on '<object>' elements in order to provide meaning to screen reader and other assistive technology users, as these technologies are unable to translate non-text content.

Contrast

Background and foreground colors have a sufficient contrast ratio
Many (if not most) users find low-contrast text difficult or impossible to read.

Tables and lists

`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements.
Screen readers and other assistive technologies may produce poor and inaccurate output when definition lists are not properly marked up.

Definition list items are wrapped in `<dl>` elements
In order for screen readers and other assistive technologies to properly announce definition list items ('<dt>' and '<dd>'), they must be wrapped in parent a '<dl>' element.

Presentational `<table>` elements avoid using `<th>`, `<caption>` or the `[summary]` attribute.
It is advised to not include data elements in tables which are used for layout purposes, as it may create confusion for screen reader and other assistive technology users.

Lists contain only `<li>` elements and script supporting elements (`<script>` and `<template>`).
Use proper list structure to aid screen readers and other assistive technologies.

List items (`<li>`) are contained within `<ul>` or `<ol>` parent elements
In order for screen readers to announce list items, ensure that list items ('<li>') are contained within parent '<ul>' or '<ol>' tags.

Cells in a `<table>` element that use the `[headers]` attribute refer to table cells within the same table.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that '<td>' cells using the headers attribute only refer to other cells in the same table, to improve screen reader user experience.

`<th>` elements and elements with `[role="columnheader"/"rowheader"]` have data cells they describe.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that table headers refer to some set of cells, to improve screen reader user experience.

Internationalization and localization

`<html>` element has a valid value for its `[lang]` attribute
Specify a valid BCP 47 language in order to help screen readers and other assistive technologies announce text properly.

`[lang]` attributes have a valid value
Specify a valid BCP 47 language on elements in order to help screen readers and other assistive technologies announce text properly.

Best practices

The document does not use `<meta http-equiv="refresh">`
Pages that refresh automatically cause a poor user experience as focus is directed back to the top of the page unexpectedly.

`[user-scalable="no"]` is not used in the `<meta name="viewport">` element and the `[maximum-scale]` attribute is not less than 5.
For users with low vision who rely on screen magnification, ensure that zooming is not disabled.

Audio and video

`<video>` elements contain a `<track>` element with `[kind="captions"]`
Cn.com may provide assistance to deaf or hearing-impaired users with captions on videos.

`<video>` elements contain a `<track>` element with `[kind="description"]`
Cn.com may provide relevant information that dialogue cannot, by using audio descriptions.

Internationalization and localization

`<html>` element does not have a `[lang]` attribute
It is advised to provide a lang attribute so that screen readers and other assistive technologies are guaranteed to announce the page's text correctly. When not provided, the user's default language setting will be used which may cause inaccuracies.

Progressive Web App

Indicates how valid the aspects of a Progressive Web App (PWA) are for the page and highlights opportunities to enable/improve the PWA of cn.com. This includes details about web app manifests.

Fast and reliable

Page load is fast enough on mobile networks
Ensure that the page loads fast enough over a cellular network, to ensure good mobile user experience.

PWA Optimized

Redirects HTTP traffic to HTTPS
It is advised to redirect all HTTP traffic to HTTPS, in order to enable secure web features for all users.

Content is sized correctly for the viewport
Ensure that the width of the app's content matches the width of the viewport, otherwise the app might not be optimized for mobile screens.

Fast and reliable

Current page does not respond with a 200 when offline
In order for Progressive Web Apps to be made available offline, ensure that the app is using a service worker.

`start_url` does not respond with a 200 when offline
Consider using a service worker for Progressive Web Apps to ensure greater reliability for the user, in the case of poor network conditions.

Installable

Does not use HTTPS — 1 insecure request found
Ensure that all pages are protected with HTTPS (including those that do not handle sensitive data) as HTTPS prevents tampering and passive listening on communications between the app and its users. Additionally, HTTPS is a prerequisite for HTTP/2 and many new web platform APIs.

Insecure URL
http://cn.com/

Show Details

Does not register a service worker that controls page and `start_url`
A service worker is used to provide Progressive Web Apps the use of features such as working offline, the ability for the app to be added to the homescreen as well as push notifications.

Web app manifest does not meet the installability requirements
User engagement may be increased by leveraging the browsers ability to proactively prompt users to add the app to their homescreen.
View Data

PWA Optimized

Is not configured for a custom splash screen
Themed splash screens ensure a high-quality user experience at launch for app users.
View Data

Does not set a theme color for the address bar.
A theme may be applied to the browser address bar, which ideally can be made to match the site.
View Data

Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
It is advised to use a '<meta name="viewport">' tag for the optimization of cn.com on mobile screens.

Does not provide fallback content when JavaScript is not available
Apps should display alternative content for when JavaScript is disabled.

Does not provide a valid `apple-touch-icon`
iOS users of Progressive Web Apps will benefit from an apple touch icon, which can be defined with 'apple-touch-icon', which must point to a non-transparent 192px (or 180px) square PNG.

Manifest doesn't have a maskable icon
Maskable icons are great to ensure that images fill the entire shape when installing the app on a device.

Manual Checks

Site works cross-browser
Ensure that the Progressive Web App works correctly across every major browser.

Page transitions don't feel like they block on the network
Users perceive apps with responsive, snappy transitions as higher peforming and ensures a great user experience, even on a slow network.

Each page has a URL
Ensure that all pages are deep linkable via URL. They should also be unique for the purpose of shareability on social media.
