text-size-adjust on desktop

Pre-131, text-size-adjust was a mobile-only safety hatch. Chrome 131 honours it on desktop too, so authors can opt user-driven font scaling in everywhere. Drag the slider to see the rendered text rescale.

headline of a piece

Paragraph copy at a comfortable reading size. With text-size-adjust on, the user's accessibility scale or the per-element override applies everywhere, including on desktop. Move the slider above to see this paragraph rescale.

Set text-size-adjust: 100% to lock the page at the author size; pick a higher percentage to apply a multiplier; auto defers to the user's preference.
