我将滚动条的拇指颜色改为蓝色:


的数据
然而,拇指一直在显示。
无论如何,可以让它显示只有滚动就像浏览器一样?
下面是我的代码,你可以复制和测试:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <style>
      div#scrollable {
        border: 5px red solid;
        width: 150px;
        height: 200px;
        overflow-y: auto;
      }

      ::-webkit-scrollbar {
        width: 6px;
      }

      ::-webkit-scrollbar-thumb {
        background: blue;
        border-radius: 3px;
      }
    </style>
  </head>

  <body>
    <div id="scrollable">
      <p style="height: 1000px">my text</p>
    </div>
  </body>
</html>

使用下面的代码来显示滚动条时,你可以向上或向下滚动根据您的要求。

(function(timer) {
    window.addEventListener('load', function() {
        var el = document.querySelector('.scrollable');
        el.addEventListener('scroll', function(e) {
            (function(el) {
                el.classList.add('scroll');
                clearTimeout(timer);
                timer = setTimeout(function() {
                    el.classList.remove('scroll');
                }, 500);
            })(el);
        })
    })
})();
.scrollable {
    border: 5px red solid;
    width: 150px;
    height: 200px;
    overflow-y: auto;
}

::-webkit-scrollbar {
    width: 0px;
}

.scrollable.scroll::-webkit-scrollbar {
  width: 6px;
}

::-webkit-scrollbar-thumb {
    background: blue;
    border-radius: 3px;
}
<div class="outer">
    <div id="scrollable" class="scrollable">
        <p style="height: 1000px">my text</p>
    </div>
</div>

const scrollableDiv = document.getElementById('scrollable');
      scrollableDiv.addEventListener('scroll', () => {
        const thumb = scrollableDiv.querySelector('::-webkit-scrollbar-thumb');
        thumb.style.opacity = '0.6';
        clearTimeout(scrollableDiv.dataset.scrollTimeout);
        scrollableDiv.dataset.scrollTimeout = setTimeout(() => {
          thumb.style.opacity = '0';
        }, 1000); // Adjust this timeout to control how long the thumb stays visible after scrolling stops
      });
div#scrollable {
        border: 5px red solid;
        width: 150px;
        height: 200px;
        overflow-y: auto;
