What is the role of the imagesizes and imagesrcset attributes in the <link> element?

The imagesizes and imagesrcset attributes enable responsive image loading.

The imagesizes attribute specifies the sizes of images to preload, while the imagesrcset attribute defines a set of image sources. These attributes allow the browser to select the most suitable image size and source based on the device's display characteristics, such as resolution and size. This ensures that the best-suited image is preloaded for the user's device, enhancing performance and user experience.

<link rel="preload" as="image" href="image.jpg" imagesizes="(max-width: 600px) 100vw, 50vw" imagesrcset="image-1x.jpg 1x, image-2x.jpg 2x" />
