Introduction¶

When Mobile Accessibility is enabled, Optimize does an additional scan of the website to simulate how it renders on a mobile device. This data is used to pick up device-specific code that only loads when a website opens on a mobile device. Based on this mobile rendition of the website, we can perform two additional checks in addition to the accessibility checks that already run on the website.

These checks determine if a web page is properly responsive. Responsiveness is a basic requirement for an accessible website. The checks are displayed in the user interface and can be filtered out of the other checks. They are also displayed in the web browser extension.

• Check 1: Is pinch-to-zoom disabled?
  Some websites have, on purpose, disabled the option for visitors to be able to zoom in on a web page by pinching with their fingers. This is not an accessible experience, as visually impaired users should always have a zoom option, even on a mobile device. This check generates a flag if pinch-to-zoom is disabled.
• Check 2: Does the web page require two-dimensional scrolling?
  If a website is not properly responsive, there might be scenarios where a user needs to scroll both vertically and horizontally to read a paragraph of text or view an image. Typically, this happens if a website owner has not defined the image size for mobile devices, and the image displays in the same size as it would on a desktop computer (meaning that the visitor needs to scroll up and down and sideways to view all of the content.) This is not an accessible experience for visually impaired users and users who have motor disabilities (it is very strenuous for your wrist or arm to scroll in two dimensions.) This check generates a flag if a web page requires two-dimensional scrolling.

This article provides instructions on how to set up and use Mobile Accessibility scans.

Enable mobile scans¶

This section gives instructions on how to enable mobile scans on a website,

1. Contact support and request Mobile Scans for the website.
2. Select a Mobile Guideline:
   • WCAG 2.1 AA mobile
   • WCAG 2.1 AAA mobile.

For more information on how to select a guideline for your domain, see the Setup section in the user guide article:

Accessibility feature introduction.

Disable Mobile Scans¶

This section gives instructions on how to disable mobile scans on a website.

1. Contact support and make a request to disable mobile scans.

   Important

   When the mobile scan is disabled, it applies to all domains in the user plan. This feature is closely tied to accessibility scans and the feature must be turned off from the support team end. No accessibility scans are done until the accessibility feature is turned on again and reconfigured. You can set this up. See the links below for instructions.

2. Turn on and configure accessibility scans for each domain on the account.

   For more information, see the user guide articles:

   • Domain scan setup
   • Accessibility.

Filter for mobile-only error type¶

To filter for mobile-only issues and errors:

1. Click Accessibility (icon of a human with outstretched arms) on the top menu bar to navigate to the Accessibility module.

   
2. Click Checklist on the left menu.
3. 

4. Click Filter. The Filters list expands.

   

5. Select Accessibility error type. The error type list expands.

   
6. Select Mobile only.
7. Select a mobile-specific error:
   • Pinch-to-zoom
   • Two-dimensional scrolling.
8. The filter is only visible if the scan is set to perform the mobile scan.
9. These issues can also be found in the Accessibility module in the Pages with Failing Checks section.
