消除行内块元素左右之间的间隙

标签: css

浏览器在渲染页面的时候，会将多个标签之间的换行符，空格渲染成间隙，这些换行符属于文本节点

<!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>
        .list{       
            background-color: aliceblue;     
        }
        .item{
            width: 100px;
            height: 100px;
            background-color: brown;
            display: inline-block;
        }
    </style>
</head>
<body>
    <div class="list">     
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
    </div>
</body>
</html>

1 可以使用给父元素设置font-size:0

  .list{       
            background-color: aliceblue; 
            font-size: 0;    
        }

2 给父元素设置为弹性布局

.list{       
            background-color: aliceblue; 
            display: flex;  
        }

3 margin设置为负值

<style>
        .list{       
            background-color: aliceblue; 
        }
        .item{
            width: 100px;
            height: 100px;
            background-color: brown;
            display: inline-block;
            margin: -2px;
        }
 </style>
 <div class="list">     
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
  </div>

4 所有的标签写在一行

<div class="list">     
        <div class="item"></div><div class="item"></div><div class="item"></div>
 </div>

5 在标签后面加上注释

 <div class="list">     
        <div class="item"></div><!--     
        --><div class="item"></div><!-- 
        --><div class="item"></div>
    </div>

6 使用浮动布局

<style>
        .list{       
            background-color: aliceblue; 
        }
        .item{
            width: 100px;
            height: 100px;
            background-color: brown;
            float: left;
        }
