spz-intersection-observer-polyfill
When to use
spz-intersection-observer-polyfill installs the IntersectionObserver API polyfill for browsers that do not support it natively. This is a service component — it has no visible UI and requires no configuration.
Usage
Include the script tag on the page. The polyfill is automatically installed when the component loads:
Notes
- This is a service extension, not a visual component. It has no attributes, actions, events, or layout.
- The polyfill is only installed when the browser does not have native
IntersectionObserversupport. - Other SPZ components that rely on
IntersectionObserverwill benefit automatically.
