很久以前，我按照教程为我的网站创建了一个 3 列布局;它曾经在每个浏览器中都能正常工作，但现在使用 Chrome 它会在页面上的任何其他元素之前添加一个空白区域。
这是一段CSS和html代码：
*{margin:0; padding:0;}
body {
font-family: "Gill Sans Mt", Arial, Helvetica;
text-align:center;
}
img { border: none }
body, html, #wrapper {
width:100%;
height:100%;
position:relative;
}
#wrapper {display: table;}
#left {
position:absolute;
left:0;
top:0;
width:125px;
height:100%;
background-image:url(https://awranking.altervista.org/images/tile_sx1.jpg);
background-repeat:repeat-y;
z-index:-1;
display: table-cell;
}
#right {
position:absolute;
right:0;
top:0;
width:125px;
height:100%;
background-image:url(https://awranking.altervista.org/images/tile_dx1.jpg);
background-repeat:repeat-y;
z-index:-1;
display: table-cell;
}
#middle {
display: table-cell;
height:100%;
margin-bottom:30px;
padding-bottom:30px;

使用position: absolute真的不应该用于构建您的主布局，它应该主要用于在您的页面中精确定位内容，例如模态或对话框。
您应该使用display: inline-block或 CSS 网格或 CSS Flexbox。
使用 CSS Grid，如果要设置 3 列布局，只需在父容器上使用display: grid，grid-template-columns: 1fr 1fr 1fr立即创建 3 列。
#container {
display: grid;
grid-template-columns: 1fr 1fr 1fr;
}
#column-1 {
background-color: red;
}
#column-2 {
background-color: blue;
}
#column-3 {
background-color: yellow;
}<div id="container">
<div id="column-1">A</div>
<div id="column-2">B</div>
<div id="column-3">C</div>
</div>您可以使用此代码 -- 使用 3 列布局，带引导程序 设计响应式
