Accessibility Checker upgraded to Axe Core 4.5

by Jaime Iniesta

We've upgraded our Accessibility validation servers to the latest version of axe-core, 4.5, which introduces a new WCAG 2.2 rule to check the target size. We've also enabled 7 experimental rules that existed in previous releases of axe-core.

New WCAG 2.2 rule to test for a minimum size of touch targets

Axe-core’s new target-size rule tests if links, buttons, form fields, and other controls have a width and height of at least 24 pixels, or if they don’t, that they have that much space from the closest other control. This helps people who are less accurate in using a mouse or touchpad from accidentally activating the wrong control. For more information on target size, see understanding 2.5.8 Target Size.

7 experimental rules now enabled

css-orientation-lock

Checks that content does not restrict its view and operation to a single display orientation, such as portrait or landscape, unless a specific display orientation is essential.

Checks all interactive elements in the focus order to ensure that the role attribute value is valid and appropriate, whether native HTML or a custom ARIA widget.

Checks CSS style property values of display: none; and visibility: hidden; and alerts users to the presence of hidden item content requiring further review.

label-content-name-mismatch

For each user interface component that includes a visible text label, the accessible name must match (or include) the visible text in the label.
