How Can I Control the Scroll Speed of a Div Using CSS or jQuery?

Controlling Scroll Speed with CSS or jQuery

In an effort to optimize user experience on web pages, it becomes necessary to fine-tune certain aspects of the website, one of which is the speed at which a page scrolls. In this case, the inquiry is specifically about reducing the scroll speed of a div's content, particularly when using the mouse wheel.

Using CSS

残念ながら、CSS does not provide any direct means to control the scroll speed of an element. However, it can be used to set certain properties that may indirectly influence the perceived scroll speed. For instance, by adjusting the height of the div or the overflow properties, you can potentially slow down the scroll speed. However, these methods often require trial and error and may not provide precise control over the scroll speed.

Using jQuery

JavaScript, and by extension libraries like jQuery, offer more flexibility in controlling scroll speed. The code provided by Toni Almeida below demonstrates how to adjust the scroll speed of a div using jQuery. When the user scrolls using the mouse wheel, the function handle is triggered, calculating the delta (the amount of scrolling). It then animates the scrollTop property of the html and body elements to move the content smoothly over a specified duration and distance.

  function handle(delta) {
      var time = 1000;
      var distance = 300;

      $('html, body').stop().animate({
          scrollTop: $(window).scrollTop() - (distance * delta)
      }, time );
  }

This approach provides precise control over the scroll speed and allows for customization of the animation duration and distance. It's worth noting that the scroll speed may vary slightly depending on the browser and operating system used, and further refinement may be necessary to achieve optimal results.
