Screenshot Examples · Example 2 of 2 in Custom Styles

Inject a Stylesheet by URL

GEThttps://api.deepinfo.com/v1/lookup/screenshot

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

Param: css_url
Value: https://example.com 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.
