How to Fix Manual Scrolling Issue in a Scrolling News Widget?

Tags: Web development

Hey TechRepublic community! 👋

I’m currently working on a tool for my website that displays the latest news in a scrolling format. The idea is simple: the news scrolls up automatically, and when a user hovers over it, the auto-scroll stops, and manual scrolling is enabled.

Everything works perfectly except one annoying issue — while I can scroll down manually just fine, I can’t scroll back to the top of the news. It’s like the manual scroll refuses to move upward but has no problem going downward.

Here’s a quick breakdown of what I’ve done so far:

HTML/CSS setup: Basic marquee-style news scrolling with overflow: hidden for the container.
JavaScript integration: Added onmouseenter to pause auto-scroll and onmouseleave to resume it. Manual scrolling is controlled via overflow: auto on hover.
Issue debug attempts: Tried tweaking scrollTop in JavaScript and experimented with various CSS properties like overflow-y: scroll, but no luck fixing the upward scroll.
I’m wondering if this might be a JavaScript issue, browser compatibility problem, or something I’ve missed entirely.

Has anyone faced a similar issue or have insights on how I could resolve this? If there’s a library or a more robust approach to creating a scrolling news widget, I’m open to suggestions too.

Thanks in advance for your help! 😊

The issue with not being able to scroll up may be caused by a conflict between automatic and manual scrolling. Here are possible solutions:

Stop auto-scrolling: Ensure that auto-scrolling completely stops when the user hovers over the news.

Check overflow property: Make sure the overflow is set to auto on hover, not hidden or scroll.

Event conflict: Check for delays in applying the overflow: auto style when hovering.

Content height: Ensure the content inside the container is taller than the container itself to allow upward scrolling.

Cross-browser compatibility: Test in different browsers (Chrome, Firefox, Safari) as the issue might be browser-specific.

scrollTop reset: If scrolling up still doesn’t work, try forcing the scroll position to update when hovering.

These steps should help resolve the issue and ensure smooth scrolling.

To fix a manual scrolling issue in a scrolling news widget, follow these steps:

1. Check CSS for overflow issues: Ensure the container has the correct settings for scrolling. Adjust the 10s in the animation to control the scrolling speed.
2. Ensure JavaScript/Autoplay is set up: Check the script to ensure it triggers automatic scrolling.
3. Fix manual scrolling problem: Ensure overflow is properly set: The overflow: auto or overflow-y: scroll property should be set on the container of the widget.
4. Review the HTML structure: Ensure the container wraps the content and the content is long enough to overflow for scrolling.
5. Test responsiveness: If the widget is not scrolling as expected on certain screen sizes or devices, adjust the CSS for different screen sizes using media queries.
