CSS自定义滚动条在div

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

或者像这样使用:

var MiniScroll=function(a,b){function e(){c.scrollUpdate()}function f(){var a=new Date,b=Math.abs(a-c.animation.frame),d=c.countScrollHeight();c.animation.frame=a,c.render(b),d.height!=c.controls.height&&(e(),c.controls.height=d.height),requestAnimationFrame(f)}function g(){c.scrollUpdate()}function h(a){var b=c.target.scrollTop,d=Math.abs(a.wheelDeltaY/(10-c.speed));c.target.scrollTop=a.wheelDeltaY>0?b-d:b+d,c.scrollUpdate()}function i(a){if(a.target.classList.contains("scroll"))return a.preventDefault(),!1;var b=c.countScrollHeight();c.target.scrollTop=a.offsetY*b.mul-parseInt(b.height)/2,c.scrollUpdate()}b=b||{};var c=this,d={speed:"speed"in b?b.speed:7};this.target=document.querySelector(a),this.animation={frame:new Date,stack:[]},this.identity="scroll"+parseInt(1e5*Math.random()),this.controls={place:null,scroll:null,height:0},this.speed=d.speed,this.target.style.overflow="hidden",this.draw(),requestAnimationFrame(f),this.target.onscroll=g,this.target.addEventListener("wheel",h),this.controls.place.onclick=i};MiniScroll.prototype.scrollUpdate=function(){this.controls.place.style.height=this.target.offsetHeight+"px";var a=this.countScrollHeight();this.controls.scroll.style.height=a.height,this.controls.scroll.style.top=a.top},MiniScroll.prototype.countScrollHeight=function(){for(var a=this.target.childNodes,b=parseInt(this.target.offsetHeight),c=0,d=0;d<a.length;d++)a[d].id!=this.identity&&(c+=parseInt(a[d].offsetHeight)||0);var e=this.target.offsetHeight*parseFloat(1/(parseFloat(c)/this.target.offsetHeight)),f=this.controls.place.offsetHeight*(this.target.scrollTop/c)+"px";return{mul:c/this.target.offsetHeight,height:e>b?b+"px":e+"px",top:f}},MiniScroll.prototype.draw=function(){var a=document.createElement("div"),b=document.createElement("div");a.className="scroll-place",b.className="scroll",a.appendChild(b),a.id=this.identity,this.controls.place=a,this.controls.scroll=b,this.target.insertBefore(a,this.target.querySelector("*")),this.scrollUpdate()},MiniScroll.prototype.render=function(a){for(var b=0;b<this.animation.stack.length;b++){var c=this.animation.stack[b],d=parseInt(c.target);c.element.style[c.prop]=d+c.points}};

并初始化:

<body onload="new MiniScroll(this);"></body>

和自定义:

.scroll-place { // ... // }
.scroll { // ... // }

请检查这个链接。带有工作演示的示例

   #style-1::-webkit-scrollbar-track
{
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
    border-radius: 10px;
    background-color: #F5F5F5;
}

#style-1::-webkit-scrollbar
{
    width: 12px;
    background-color: #F5F5F5;
}

#style-1::-webkit-scrollbar-thumb
{
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,.3);
    background-color: #555;
}

下面是一个适用于Chrome和Safari的webkit示例:

CSS:

::-webkit-scrollbar 
{
    width: 40px;
    background-color:#4F4F4F;
}

::-webkit-scrollbar-button:vertical:increment 
{
    height:40px;
    background-image: url(/Images/Scrollbar/decrement.png);
    background-size:39px 30px;
    background-repeat:no-repeat;
}

::-webkit-scrollbar-button:vertical:decrement 
{
    height:40px;
    background-image: url(/Images/Scrollbar/increment.png);    
    background-size:39px 30px;
    background-repeat:no-repeat;
}

输出:

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

我尝试了很多插件，他们中的大多数不支持所有的浏览器，我更喜欢iScroll和nanoScroller适用于所有这些浏览器:

Ie11 -> ie6 Ie10 - wp8 Ie9 - wp7 IE Xbox One IE Xbox 360 谷歌Chrome 火狐歌剧 Safari

但iScroll不工作与触摸!

在Firefox +64中只使用CSS

.mycoldiv{
    scrollbar-color: white rebeccapurple;
    scrollbar-width: thin;
    display: block;
    height:400px;
    overflow-x: auto;
}
