Enable Accessibility Enhancements for Page Headers and Modal Windows When Zoom Is Greater Than 200% (Release Update)

To help meet Web Content Accessibility Guidelines (WCAG) 2.2 for Resize and Reflow, enable Lightning Experience to adapt the behavior of page headers and modal windows when viewed at high magnification. This is the beginning of our effort to comply with WCAG 2.2 Resize and Reflow guidelines. Expect accessibility enhancements to other UI elements in future release updates. This update was first available in Summer ’25 and was scheduled to be enforced in Summer ’26, but we postponed the enforcement date to Winter ’27.

Where: This change applies to Lightning Experience in all editions.

When: This update is postponed to Winter ’27. To get the major release upgrade date for your instance, go to Trust Status, search for your instance, and click the Maintenance tab.

Why: With this update, content is visible for users who view Salesforce via a browser at 200% magnification or greater.

Without this update, you can have trouble seeing the content on a page when you zoom in over 200%. The page headers can block content as you scroll. In modal windows, buttons and other content can display outside the viewport, requiring horizontal scrolling, which can make modal windows unusable.

These changes help you support users who want to zoom 300% to 400%.

The page header scrolls with the page and doesn’t block the content.

In modal windows, buttons and content display within the viewport and the window is fully functional.

How: To review this update, from Setup, in the Quick Find box, enter Release Updates, and then select Release Updates. For Enable Accessibility Enhancements for Page Headers and Modal Windows When Zoom Is Greater Than 200%, follow the testing and activation steps.
