# Lazy load
-You can use `lazy` to let image load after it enters viewport.
+Load the images only after they enter the viewport. There are two ways to use it: one is to use the `lazy` property alone, which will be set to the value of the [HTMLImageElement.loading](https://developer.mozilla.org/en-US/docs/Web/API/HTMLImageElement/loading) property, and the other is to use `lazy` together with the `intersection-observer-options` configuration to implement lazy loading using the [IntersectionObserver](https://developer.mozilla.org/en-US/docs/Web/API/IntersectionObserver) API.
