<picture> allows serving different images based on media queries or format support (art direction and responsive images), letting the browser pick the best matching <source> before falling back to the default <img>.
<picture> <source media="(min-width: 800px)" srcset="large.jpg"> <source media="(min-width: 400px)" srcset="medium.jpg"> <img src="small.jpg" alt="Product photo"> </picture>
