今天面试题 记录

今天主要问的都是一些基础的知识，自己心里知道大概是那样，但是就是答不好，还是自己没研究深刻。

标准盒模型和ie盒模型

 

3:border-box和content-box的区别

1.盒子模型尺寸基准有两种，分别是content-box和border-box  （默认是content-box）

2.理论上说，content-box与border-box区别是两者的盒子的宽度是否包含表框和内边距。

3.新建两个不同背景填充的div,

(con1设置为box-sizing：border-box，con为默认的content-box)
<head lang="en">  
    <meta charset="UTF-8">  
    <title></title>  
    <style>  
        .con{width: 100px; height: 100px;background-color:royalblue;  
            border:1px solid red; padding: 10px;}  
        .con1{box-sizing: border-box;}  
    </style>  
</head>  
<body>  
    <div class="con"></div>  
    <div class="con con1"></div>  
</body>

效果图如下：

 

其他的暂时想不起来了。。。
