Changing the color of an SVG as I scroll to the bottom of the page

On my React page, I am looking to change the color of an SVG element from black to white at the bottom of the page. Is there a React-specific method for accomplishing this task? The div container located at the bottom of the page is not the parent div for the SVG, as it is actually part of a stickied header.

Answer №1

If you want to check whether a user has scrolled to the bottom of a page, you can use event listeners on scroll events and then analyze the scrollHeight, scrollTop, and clientHeight properties of a node. For examples of how this can be implemented effectively, take a look at responses to a related question here.

Answer №2

It's important to note that the issue at hand is more closely tied to SVG itself rather than React.

Have you considered whether your SVG is being included as an <img ...> tag or if it's inline?

If it's presented as an image tag, implementing filters could be a viable solution.

However, for intricate SVG images with various colors, I suggest converting it into a component and utilizing it as inline code.

This approach offers greater control over the SVG elements, allowing you to easily modify the fill of paths or shapes to fill: white.

In terms of handling its position on the page, there are several options available. You could monitor scroll position in relation to viewport height, or opt for a specific solution like React Waypoint for more targeted functionality.
