我的水平线从网页的第三条开始，但是让线向下移动一点（也许是200-400px？）让我感到非常痛苦。每当我尝试使用“ top：-200px;”在样式元素（中线）内，它只会使一半的线消失
<html>
<header>
<style>
.divider{
position:absolute;
left:33.3%;
top:0%;
bottom:0%;
border-left:5px solid black;
}
.divider2{
position:absolute;
left:66.6%;
top:0%;
bottom:0%;
border-left:5px solid black;
}
#left {
width:380px;
float:left;
margin-left: 100px
}
#middle {
width:380px;
float:right;
text-align:center;
margin-right: 300px
}
#right {
width:380px;
float:right;
margin-left: 40px
}
#midline{
position:relative;
left:530px;
width:1265px;
height:5px;
background: black;
}

最佳答案
省略bottom设置并设置top: 200px;（不是减号，而是加号-到顶部的距离）。顺便说一句：一条规则中的顶部和底部太多，其中之一就足够了。
