css + div 列表布局

常见列表布局，效果如下图。常见图与图之间经常会留间距，下图图与图没留间距

1、第一种列表布局：float + margin

 

1.2、第一种列表布局相应代码

<!DOCTYPE html>
<head>
<title>float+margin布局，最开始或者最后元素会留间距。</title>
<style>
    *{
        margin: 0;
        padding:0;
    }
   .row{
     margin: 10px auto;
     width:500px;
     height:200px;
     border:1px solid red;
    }
    .col{
        width:100px;
        height:100px;
        background: yellow;
        float: left;
        border:1px solid black;
        margin-right: 23px;
    }
</style>
</head>

 <body>
	<div class="row">
		<div class="col">1</div>
		<div class="col">2</div>
		<div class="col">3</div>
		<div class="col">4</div>
	</div>
  </body>
</html>

2、第二种列表布局：float + border(border充当间距)

解析：第二种方式开始列没有给间距

 

2.2、第二种列表布局相应代码

<!DOCTYPE html>
<head>
<title>float + border,border充当间距</title>
<style>
    *{
        margin: 0;
        padding:0;
    }
   .row{
     margin: 10px auto;
     width:500px;
     height:200px;
     border:1px solid red;
    }
    .col{
        width:125px;
        height:100px;
        background: yellow;
        float: left;
		margin-bottom:5px;
    }
    .border-color-gap{
        box-sizing: border-box;
        border-left:10px solid #ffffff;
    }
</style>
</head>
    <body>
		<div class="row">
			<div class="col">1</div>
			<div class="col border-color-gap">2</div>
			<div class="col border-color-gap">3</div>
			<div class="col border-color-gap">4</div>
			<div class="col">3</div>
			<div class="col border-color-gap">4</div>
			<div class="col border-color-gap">3</div>
			<div class="col border-color-gap">4</div>
		</div>
	</body>
</html>3

3、第三种列表布局：display: flex;flex-direction: row + margin

	<title>flex布局</title>
	<style>
		*{
			margin: 0;
			padding:0;
