Foreign Pick: You May Not Need a Bundler for Your NPM Library

Content‑Visibility Re‑Explored: A Viable Lazy‑Load Alternative?

Key conclusions from the investigation are:

Applying content-visibility: hidden prevents the browser from re‑rendering an element and its children, improving toggle performance. content-visibility: auto behaves like a virtual list, dramatically boosting rendering performance for long lists or text pages.

Using contain-intrinsic-size to estimate the size of content-visibility: auto elements avoids scroll‑bar jitter during scrolling. content-visibility: auto cannot fully replace LazyLoad because resources inside off‑screen elements are still loaded during page initialization.

Elements with content-visibility: auto that are not rendered do not interfere with global search functionality.
