content-visibility: the new CSS property that boosts your rendering performance
Effects on Interaction to Next Paint (INP)
INP is a metric that evaluates a page's ability to be reliably responsive to user input. Responsiveness can be affected by any excessive amount of work that occurs on the main thread, including rendering work.
Whenever you can reduce rendering work on any given page, you're giving the main thread an opportunity to respond to user inputs more quickly. This includes rendering work, and using the content-visiblity CSS property where appropriate can reduce rendering work—especially during startup, when most rendering and layout work is done.
Reducing rendering work has a direct effect on INP. When users attempt to interact with a page that uses the content-visibility property properly to defer layout and rendering of offscreen elements, you're giving the main thread a chance to respond to critical user-visible work. This can improve your page's INP in some situations.
