CLI: `--image-selector` · REST: [`image_selector`](https://zshot-cli.com/reference/server/api/schema/#image_selector)
Value: `SELECTOR`

Crops the image to the element matching this CSS selector. The element's size will determine the output size, which [`--image-width`](/reference/flags/image/image-width) and [`--image-height`](/reference/flags/image/image-height) override. An invalid or selector that matches nothing will cause an error.
