第一步:上框架和div
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
</head>
<style>
#bodys{
width: 600px;
height: 600px;
background: wheat;
}
.one{
width: 100px;
height: 100px;
background-color: lawngreen;
}
.two{
width: 100px;
height: 100px;
background-color: darkgoldenrod;
}
.three{
width: 100px;
height: 100px;
background-color: darkmagenta;
}
</style>
<body>
<div id="bodys">
<div class="one">
</div>
<div class="two">
</div>
<div class="three">
</div>
</div>
</body>
</html>
第二步:今天我们来认识一下justify-content
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
*{
margin: 0;
padding: 0;
}
ul{
width: 500px;
height: 200px;
margin: 20px;
border: 2px solid black;
/* 设为弹性盒子 */
display: flex;
}
li{
/* 去除默认样式 */
list-style: none;
width: 50px;
border: 1px solid red;
text-align: center;
font-size: 20px;
}
ul:nth-of-type(1){
/* 主轴开始对齐(默认值)*/
justify-content: flex-start;
}
ul:nth-of-type(2){
/* 主轴结束对齐 */
justify-content: flex-end;
}
ul:nth-of-type(3){
/* 主轴居中对齐 */
justify-content:center;
}
ul:nth-of-type(4){
/* 主轴两端对齐 */
justify-content:space-between;
}
ul:nth-of-type(5){
/* 2边间距和中间间距的比值是1:2 */
justify-content:space-around;
}
ul:nth-of-type(6){
/* 2边间距和中间间距的比值是1:1 */
justify-content:space-evenly;
}
</style>
