原理就是在一個層上加二到三個層,不過這些層只有左右邊線,最上和最下有背景色,然後它們都有長度差距,就這樣了,以下是我做的例子:
<html
<head>
<title>無標題頁</title>
<style>
.up1
{
overflow:hidden;
height:1px;
margin-left:4px;
margin-right:4px;
background-color: Aqua;
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.up2
{
overflow:hidden;
height:1px;
margin-left:3px;
margin-right:3px;
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.up3
{
overflow:hidden;
height:1px;
margin-left:2px;
margin-right:2px;
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.content
{
margin-left:1px;
margin-right:1px;
height:100px;/*這裡控制項高度*/
/*background-color: Aqua;*/
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.down1
{
overflow:hidden;
height:1px;
margin-left:2px;
margin-right:2px;
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.down2
{
overflow:hidden;
height:1px;
margin-left:3px;
margin-right:3px;
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.down3
{
overflow:hidden;
height:1px;
margin-left:4px;
margin-right:4px;
background-color: Aqua;
border-left:solid 1px Aqua;
border-right:solid 1px Aqua;
}
.cell
{
width: 50px;/*這裡控制寬度*/
}
</style>
</head>
<body>
<div class="cell">
<div class="up1">

<div class="up2">
</div>
<div class="up3">

<div class="content">
這裡放內容
</div>
<div class="down1">

<div class="down2">

<div class="down3">
