What is the primary effect of setting ‘content-visibility: auto’ on a complex DOM subtree?

Accepted Answer

The 'content-visibility: auto' property allows the browser to skip the rendering work (layout and painting) of an element's subtree if it is not currently visible in the viewport. This significantly improves initial load time and interaction latency for large pages. Option A is the opposite of the property's purpose. Option C is unrelated to rendering skipping. Option D is incorrect as it actually helps manage layout state more efficiently.
