An opacity sweep scroll panel built with pure HTML and CSS that gradually reveals content through fading transitions as the user scrolls, creating a smooth visual progression without relying on JavaScript or external libraries.
Usage
This component is ideal for interfaces where content should appear progressively, such as feature showcases, storytelling layouts, long-form sections, or panels where visual pacing improves readability and engagement.
Implementation
The sweep effect is achieved using CSS opacity control, scroll-linked positioning, and transition timing, allowing sections to fade in or out as they enter and leave the visible area while keeping the structure lightweight and reusable.
