# Responsive Media

[component-header:sl-responsive-media]

Displays media in the desired aspect ratio.

You can slot in any [replaced element](https://developer.mozilla.org/en-US/docs/Web/CSS/Replaced_element), including `<iframe>`, `<img>`, and `<video>`. As the element's width changes, its height will resize proportionally. Only one element should be slotted into the container. The default aspect ratio is `16:9`.
