我如何通过CSS(层叠样式表)为一个div而不是整个页面自定义滚动条?


当前回答

我认为你必须对所有的滚动条使用::-wekbit-scrollbar,你可以使用:

<style>
.mydiv {
height:100px;
overflow:auto;
}
     /* width */
    .mydiv::-webkit-scrollbar {
      width: 20px;
    }
    
    /* Track */
    .mydiv::-webkit-scrollbar-track {
      box-shadow: inset 0 0 5px grey; 
      border-radius: 10px;
    }
     
    /* Handle */
    .mydiv::-webkit-scrollbar-thumb {
      background: red;
      border-radius: 10px;
    }
    
    /* Handle on hover */
    .mydiv::-webkit-scrollbar-thumb:hover {
      background: #b30000; 
    }
</style>
<body>
<div class="mydiv"> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> <br/> </div>
</body>

我尝试了很多JS和CSS滚动,我发现这很容易使用,并在IE、Safari和FF上进行了测试,效果很好

正如@ theblufox所言

下面是它的工作原理

将下面的脚本添加到

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<script type="text/javascript" src="jquery.ui.touch-punch.min.js"></script>

<script type="text/javascript" src="facescroll.js"></script>

<script type="text/javascript">
    jQuery(function(){ // on page DOM load
        $('#demo1').alternateScroll();
        $('#demo2').alternateScroll({ 'vertical-bar-class': 'styled-v-bar', 'hide-bars': false });  
    })
</script>

在这段你需要滚动的地方

<div id="demo1" style="width:300px; height:250px; padding:8px; resize:both; overflow:scroll">
**Your Paragraph Comes Here**
</div>

希望能有所帮助

假设div为

<div class="custom_scroll"> ... </div>

应用CSS样式为

//custom scroll style definitions
.custom_scroll
{
  overflow-y: scroll;
}

//custom_scroll scrollbar styling
.custom_scroll::-webkit-scrollbar-track
{
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
    border-radius: 10px;
    opacity: 0.5;
    //background-color: #F5F5F5;
}

.custom_scroll::-webkit-scrollbar
{
    width: 5px;
    opacity: 0.5;
    //background-color: #F5F5F5;
}

.custom_scroll::-webkit-scrollbar-thumb
{
    border-radius: 10px;
    opacity: 0.5;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
    //background-color: #555;
}

产生的滚动将显示为

对于使用sass的人来说,这里是一个具有基本功能(拇指,轨道颜色和宽度)的mixin。我没有广泛地测试它,所以请随意指出任何错误。

@mixin element-scrollbar($thumb-color, $background-color: mix($thumb-color, white,  50%), $width: 1rem) {
  // For Webkit
  &::-webkit-scrollbar-thumb {
    background: $thumb-color;
  }

  &::-webkit-scrollbar-track {
    background: $background-color;
  }

  &::-webkit-scrollbar {
    width: $width;
    height: $width;
  }

  // For Internet Explorer
  & {
    scrollbar-face-color: $thumb-color;
    scrollbar-arrow-color: $thumb-color;
    scrollbar-track-color: $background-color;
  }

  // For Firefox future compatibility
  // This is W3C draft and does not work yet. Use html-firefox-scrollbar mixin instead.
  & {
    scrollbar-color: $thumb-color $background-color;
    scrollbar-width: $width;
  }
}

// For Firefox
@mixin html-firefox-scrollbar($thumb-color, $background-color: mix($thumb-color, white,  50%), $firefox-width: this) {
  // This must be used on html/:root element to take effect
  & {
    scrollbar-color: $thumb-color $background-color;
    scrollbar-width: $firefox-width;
  }
}

自定义滚动条无法使用CSS,您需要一些JavaScript魔法。

有些浏览器支持非规范的CSS规则,比如Webkit中的::-webkit-scrollbar,但这并不理想,因为它只能在Webkit中工作。IE也有类似的东西,但我认为他们不再支持它了。

Webkit浏览器(如Chrome, Safari和Opera)支持非标准的::-webkit-scrollbar伪元素,它允许我们修改浏览器滚动条的外观。

注意:Firefox、IE和Edge不支持::-webkit-scrollbar。
