What is the difference between `@media` and `@supports` in CSS?

The choice highlighting that @media applies styles based on media conditions is correct because @media is a CSS at-rule used to apply different styles depending on the media type or device characteristics. This includes features like screen resolution, viewport width, or device orientation. For instance, a developer might use @media to create responsive designs that adjust layouts or styles for mobile devices versus desktop displays, ensuring an optimal user experience across various devices.

The other options present misconceptions: @supports is not deprecated; it is an important tool for feature queries in CSS that checks if a particular style feature is supported by the browser. Furthermore, @supports is not limited to media queries; it is specifically designed to determine the browser's support for CSS properties, enabling developers to apply styles conditionally based on the capabilities of the user's browser. Lastly, @media does not check for property support; its primary function is to assess the environment in which the CSS is being rendered.
