`GET https://api.deepinfo.com/v1/lookup/screenshot?url=https%3A%2F%2Fexample.com&css_url=https%3A%2F%2Fcdn.jsdelivr.net%2Fnpm%2Fwater.css%402%2Fout%2Fdark.css`

A capture of example.com with a stylesheet injected from a URL (css_url): the dark theme of a public stylesheet.

Example 2 of 2 in **Custom Styles** · [Screenshot Examples](/reference/lookup/screenshot/examples/) · endpoint: [Screenshot](/reference/lookup/screenshot/)

Tags: `param` `css_url` · `value` `https://example.com` · `value` `https://cdn.jsdelivr.net/npm/water.css@2/out/dark.css`

Asks for a capture of `https://example.com` with the stylesheet `https://cdn.jsdelivr.net/npm/water.css@2/out/dark.css` injected (`css_url`).

The browser loads the stylesheet and adds it to the page before the capture, like `css` but from a file: here the dark theme of Water.css, a small public stylesheet for plain HTML pages. The response looks like any capture of `example.com`; the difference is in the image.
