<picture>: The Picture element
The browser will consider each child
<source> element and choose the best match among them. If no matches are found—or the browser doesn't support the
<picture> element—the URL of the
src attribute is selected. The selected image is then presented in the space occupied by the

type attributes to select a compatible image that best matches the current layout and capabilities of the display device.
<img> element serves two purposes:
- It describes the size and other attributes of the image and its presentation.
- It provides a fallback in case none of the offered
<source>elements are able to provide a usable image.
Common use cases for
- Art direction. Cropping or modifying images for different
mediaconditions (for example, loading a simpler version of an image which has too many details, on smaller displays).
- Offering alternative image formats, for cases where certain formats are not supported.
- Saving bandwidth and speeding page load times by loading the most appropriate image for the viewer's display.
If providing higher-density versions of an image for high-DPI (Retina) display, use
srcset on the
<img> element instead. This lets browsers opt for lower-density versions in data-saving modes, and you don't have to write explicit
