ResponsiveDevices.css – responsive device frames for your demo page

In plain words

ResponsiveDevices.css is a CSS framework that displays demo pages within realistic device frames like phones, tablets, and desktops. It's designed for developers and designers who want to showcase how their web projects look across different screen sizes. The tool uses CSS to render these device mockups directly on a page, eliminating the need for separate screenshot tools or image assets.
