How to achieve the page fixed and control element movement after scrolling to a specified position?

Implementation method of scrolling to a specified position and fixing elements when the page is moved

In web design, it is often necessary to achieve the effect of scrolling to a specific position and fixing the page while controlling the continued movement of specific elements. This enhances the user experience and creates unique visual effects. This article will explore how to implement this feature.

This effect requires precise control of page scrolling and element movement. Fortunately, some JavaScript libraries can simplify this process. The following two libraries are recommended:

1. ScrollMagic: This is a powerful JavaScript library for triggering various animations and effects when pages are scrolling. It allows to define "scenes" that perform preset actions when the scrollbar reaches these scenes. This is very effective for controlling page fixation and element movement.

2. Jarallax: This is a lightweight parallax scrolling library that easily creates parallax scrolling effects and controls how fast and direction elements move as they scroll. Although it is mainly used for parallax effects, it can also realize the movement of elements when the page is fixed through custom settings.

Using these two libraries in combination, you can achieve the effect of fixed pages after scrolling to a specified position and specific elements continue to move. The specific steps depend on your needs and page structure, but the basic idea is: use ScrollMagic to define the scene. When the scrollbar reaches the scene, the element movement controlled by Jarallax is triggered; after the element movement is completed, the fixed state of the page is released and the scrolling is allowed to continue scrolling.

Hope the above information can help you achieve the desired results.
