Question

我试图在垂直可滚动的div中有一个始终可见的滚动条，但没有使滚动条减小div中元素的宽度。基本上，我希望使用div使用“ overflow-y：scroll”的div具有浏览器的默认行为，但是在不滚动时滚动条不会消失。

我尝试了以下操作，但是如您所见，滚动条减小了div的可用宽度，

这可能吗？

如果您特别希望它可以与webkit psuedo类一起使用，那么您将需要采用这种方式

.scrollbar {
	margin-left: 22px;
	float: left;
	height: 180px;
	width: 200px;
	background: #F5F5F5;
	overflow-y: scroll;
  margin:10px;
}
.force-overflow {
	min-height: 450px;
}
#wrapper {
	text-align: center;
	margin: auto;
}
#style-1::-webkit-scrollbar {
	width: 20px;
}

/**  STYLE A */
#style-1::-webkit-scrollbar-thumb {
	border-radius: 10px;
	background-color: green;
}

#style-1::-webkit-scrollbar-track {
	border-radius: 10px;
	background-color: red;
}

<div id="wrapper">
  <div class="scrollbar" id="style-1">
    <div class="force-overflow"><h2>A</h2></div>
  </div>
</div>
<div id="wrapper">
  <div class="scrollbar" id="style-default">
    <div class="force-overflow"><h2>B</h2></div>
  </div>
</div>

请注意，-webkit-scrollbar

CSS：滚动条始终可见，而不会减小容器的宽度
