Enable Accessibility Enhancements for Page Headers and Modal Windows When Zoom Is Greater Than 200% (Release Update)
This Release Update makes Lightning Experience adapt page headers and modal windows for users viewing the browser above 200% zoom, as part of Salesforce's WCAG 2.2 Resize and Reflow effort: the page header scrolls with the page instead of covering content, and modal buttons and content stay inside the viewport. It was first offered in Summer '25 with enforcement postponed from Summer '26 to Winter '27, and the other Winter '27 accessibility Release Updates depend on this one being enabled first. Test and activate it from Setup > Release Updates before the enforcement date.
