Sometimes we need to show a zoomed in or a cropped version of an image for certain viewport sizes. This is the art direction problem. To handle this, we use the picture element with multiple sources. Each source should contain a media condition and a srcset. The browser will pick the first source whose media condition matches.
Ex:
<body>
<picture>
<!-- Display cropped image on mobile device -->
<source media="(max-width: 500px)" srcset="/images/meal-cropped.jpg" />
<!-- Display full image on larger screen -->
<source media="(min-width: 501px)" srcset="/images/meal.jpg" />
<!-- Backup image -->
<img src="/images/meal.jpg" alt="A bowl of salmon and curry" />
</picture>
</body>
