有人能看到问题吗？

Answer 1

问题是您在元素中定义了一个创建垂直滚动条的高度，如果您不需要为容器设置固定高度，则可以尝试此更改。

.scrollbar{
    width:250px;
    min-height:300px; /* min-height instead of height */
    background-color:lightgray;
    margin-top:40px;
    margin-left:40px;
    /*overflow-y:scroll;/* /*comment this line */
    float:left;
}

.content{
    min-height:450px; /* min-height instead of height */
}

Answer 2

解决：问题与此有关：conflict between overflow-y and overflow-x。我使用了链接中描述的解决方法来解决问题。不需要javascript。

＆＃13;

#wrapper {
   height: 300px;
   overflow-x: hidden;

}

.content{
    background-color:lightgray;

}

.scrollbar{
width:250px;
height: 300px;
margin-top:40px;
margin-left:40px;
float:left;
}


#ex4::-webkit-scrollbar{
width:8px;
background-color:#cccccc;
}
#ex4::-webkit-scrollbar-thumb{
background-color:#333333;
border-radius:10px;
}
#ex4::-webkit-scrollbar-thumb:hover{
background-color:#999999;
border:1px solid #333333;

}
#ex4::-webkit-scrollbar-thumb:active{
background-color:#666666;
border:1px solid #333333;
}
#ex4::-webkit-scrollbar-track{
border:1px gray solid;
border-radius:10px;
-webkit-box-shadow:0 0 2px gray inset;
}
#menuwrapper ul, #menuwrapper ul li{
    margin:0;
    padding:0;
    list-style:none;
}
#menuwrapper ul li{
   background-color: #39255e ;
    border-bottom:solid 1px white;
    width:150px;
	cursor:pointer;
}
#menuwrapper ul li:hover,
#menuwrapper ul li.iehover{
