Frequently Asked Questions
Everything you need to know about using this application.
What are CSS scroll snap points?
CSS scroll snap points are a powerful layout feature that allows developers to define snapping positions for scrollable containers. When a user scrolls through a container, the browser automatically 'snaps' the content to a specific alignment—such as the start, center, or end—providing a polished, app-like experience for sliders, carousels, and image galleries. By leveraging this native browser capability, developers can reduce the need for heavy JavaScript-based slider libraries. This leads to improved performance, lower memory usage, and a smoother interaction experience that feels integrated directly into the browser's scrolling engine.
How does this scroll snap generator work?
This tool provides an interactive playground where you can toggle various CSS properties like scroll-snap-type and scroll-snap-align in real-time. Simply select your desired axis, strictness level, and alignment preference from the control panel, and the live preview area will update instantly to show you exactly how the scroll interaction behaves. Once you are satisfied with the behavior, the tool generates the corresponding CSS snippet automatically. You can then copy this code directly into your stylesheet. The interface is designed to make complex CSS layout behavior intuitive, visual, and fast for modern web development workflows.
Is the generated CSS production-ready?
Yes, the CSS generated by this tool is standard, production-ready code. It uses the official W3C CSS Scroll Snap specification, which is widely supported across all modern web browsers including Chrome, Firefox, Safari, and Edge. We prioritize clean, semantic code that is easy to maintain within your existing projects. While the code is standards-compliant, always verify your design against your specific project requirements, particularly regarding browser prefixing or legacy support. The tool provides a reliable foundation, allowing you to focus on your design and user experience goals without getting bogged down in manual syntax writing.
Can I save my configurations for later?
To ensure the best privacy and security, this tool is entirely client-side and does not use persistent storage like cookies, localStorage, or databases. Your settings and generated code exist only within the current session's memory. If you refresh the browser page, your current configuration will be reset to the default state. We recommend copying your generated CSS code into your project's stylesheet or a text editor as soon as you are happy with the preview. This design choice ensures that the tool is lightweight, fast to load, and completely secure, as no data is ever sent to or stored on an external server.
