Solving the Mysterious Case of Scroll Snap Stops Working After Repeated Scrolling

• scroll-snap-type: x mandatory: Snap points are created along the x-axis (horizontal).
• scroll-snap-type: y mandatory: Snap points are created along the y-axis (vertical).

In addition to the `scroll-snap-type` property, you’ll need to define the snap points themselves using the `scroll-snap-align` property. This property specifies the alignment of the snap point within the container.

The Culprit: Repeated Scrolling

Now that we’ve covered the basics of scroll snap, let’s delve into the issue at hand: scroll snap stops working after repeated scrolling. You’ve applied the necessary CSS properties, and everything seems to be working just fine… until it doesn’t.

Symptoms and Troubleshooting

Here are some common symptoms and troubleshooting steps to help you identify the problem:

Solutions to the scrolled Conundrum

Now that we’ve identified some potential causes, let’s dive into the solutions:

1. Disable Scroll Anchoring

One possible culprit behind scroll snap stops working is scroll anchoring, a feature introduced in Chrome 56. To disable scroll anchoring, add the following CSS property to your scroll container:

.scroll-container {
  overflow-anchor: none;
}

2. Use `scroll-snap-type: proximity` Instead of `mandatory`

Try switching from `scroll-snap-type: mandatory` to `scroll-snap-type: proximity`. This property tells the browser to snap to the nearest snap point, rather than enforcing a strict snap point alignment.

.scroll-container {
  scroll-snap-type: y proximity;
}

3. Apply `scroll-snap-stop: always` to the Scroll Container

This property ensures that the browser will always snap to a snap point, even when the user scrolls rapidly.

.scroll-container {
  scroll-snap-stop: always;
}

4. Add a Debounce Function to Handle Repeated Scrolling

Implement a debounce function to limit the frequency of scroll events, reducing the likelihood of scroll snap stops working. You can use a JavaScript library like Lodash or create your own debounce function.

function debounce(fn, delay) {
  let timeout;
  return function() {
    const context = this;
    const args = arguments;
    clearTimeout(timeout);
    timeout = setTimeout(() => {
      fn.apply(context, args);
    }, delay);
  };
}

const scrollContainer = document.querySelector('.scroll-container');
const handleScroll = debounce(() => {
  // Your scroll event handling code here
}, 300);

scrollContainer.addEventListener('scroll', handleScroll);

Conclusion

There you have it, folks! By following these troubleshooting steps and solutions, you should be able to resolve the issue of scroll snap stops working after repeated scrolling. Remember to keep an eye out for those pesky DOM mutations, and don’t hesitate to experiment with different scroll snap properties to find the perfect fit for your project.

Final Checklist

Before you go, make sure to review this final checklist to ensure you’ve covered all your bases:

1. Verify that the `scroll-snap-type` property is correctly applied to the scroll container.

4. Disable scroll anchoring if necessary.
5. Try using `scroll-snap-type: proximity` instead of `mandatory`.
