过往的实现方法是使用浮动加计算布局来实现，当flex和grid问世时，这一切将变得简单起来
一、简单的两列实现
1、先看页面效果
2、css代码
.container {
padding: 10px;
width: 100ch;
margin: 0 auto;
box-shadow: inset 0 0 0 2px #ccc;
}
.column {
margin: 20px;
background-color: #ccc;
padding: 10px;
}
.flexbox {
display: flex;
}
.grid {
display: grid;
grid-auto-flow: column;
}3、html代码
div class="container"flex布局/div div class="container flexbox" div class="column" div class="element" p 松饼冰淇淋小熊软糖。甜苹果派，蛋糕，糖果，胡萝卜蛋糕。糖蛋奶酥，柠檬糖软糖。/p /div /div div class="column" div class="element" p提拉米苏粉布丁。蛋糕芝士蛋糕糕点焦糖提拉米苏。/p /div /div /div div class="container"grid布局/div div class="container grid" div class="column" div class="element" p松饼冰淇淋小熊软糖。甜苹果派，蛋糕，糖果，胡萝卜蛋糕。糖蛋奶酥，柠檬糖软糖。/p /div /div div class="column" div class="element" p提拉米苏粉布丁。蛋糕芝士蛋糕糕点焦糖提拉米苏。/p /div /div /div
二、每行放置3列，多出来的自动到下一行
1、还是先看页面效果
2、css代码
.container {
padding: 10px;
width: 100ch;
margin: 0 auto;
box-shadow: inset 0 0 0 2px #ccc;
}
.column {
margin: 20px;
background-color: #ccc;
padding: 10px;
}
.flexbox {
display: flex;
}
.flexbox.col-3 {
flex-wrap: wrap;
}
.flexbox.col-3 .column {
margin: 0.5rem;
width: calc((100% / 3) - 1rem);
}
.grid {
display: grid;
grid-auto-flow: column;
}
.grid.col-3 {
grid-gap: 1rem;
grid-template-columns: repeat(3, 1fr);
grid-auto-flow: unset;
}
.grid.col-3 .column {
margin: 0;
}3、html代码
