Lightning Experience gets a coordinated set of accessibility changes for users who work at high zoom levels.
Where
Standard Lightning components across the platform: cards and docked containers, menu lists and panels, date pickers and popovers, the bottom utility bar, record headers, page headers and modal windows.
How
At 200% magnification and above these components now resize and reflow instead of clipping or overlapping, following the WCAG 2.2 reflow requirement. The changes apply automatically, with no admin setup.
Why
Users with low vision routinely run browsers at 200% zoom, and hidden buttons or cut-off modals made parts of Salesforce unusable. Winter '27 also lists these as release updates, so review them in Setup and test your custom pages at high zoom.
