What is object-fit, and how is it used?

The object-fit property in CSS determines how the content of an element (like images or videos) is adjusted to fit within its container, ensuring that the scaling behavior aligns with the desired layout. It helps manage how media content is displayed without distorting its aspect ratio, especially when working with responsive design. It determines how content is scaled, ensuring it maintains its aspect ratio, or adjusts to fill or cover the container as needed. This property is especially useful in responsive design, where the content needs to adjust to different screen sizes and container shapes.

Common values of object-fit:

contain: The content is resized to fit within the container while keeping its original aspect ratio intact. If necessary, the content will be smaller than the container, leaving empty space around it.

cover: cover: The content is scaled to completely fill the container while preserving its aspect ratio. This may cause parts of the content to be cropped if the container's aspect ratio differs from the content's. The content is scaled to ensure the container is fully covered, which might cause the content to be cropped.

fill: The content stretches to completely fill the container, disregarding its aspect ratio. This may cause distortion if the container's aspect ratio differs from the content's.
