html - 调整浏览器窗口大小会干扰页面流

Question

我已将 css 应用于我的页面，当浏览器最大化时它看起来不错，但是每当我减小浏览器窗口的大小时，元素的流动就会受到干扰：

示例：http: //jsfiddle.net/rTjyV/

我的代码如下：

CSS

Answer 1

您的 css 有很多问题，例如：

1）我猜你想在浏览器中间对齐你的 div.content ，
因此

 margin-right:200px;  
 margin-left:200px;  

这不是标准方式，而是这样做：

 body{  
 background:  
 border:  
 ..........  
 margin:0 auto;  
 text-align:center;  
 }  
 .content{  
  margin:0 auto;
  margin-top:5px;  

//don't include margin-left or margin-right instead set a width for the div  

  width:800px;  
  .............  
  }  

并根据为div.content设置的宽度设置其他元素的宽度.....

Answer 2

正如@mukund 所提到的 - 主要问题在于 CSS.content以及您尝试将其居中的方式。

尝试将您的 CSS 更改为以下内容：

body{
  background:#eff3f6;
  border: 1px solid #C3D4DB;
  text-align: center;   /* added this to center any children */
}

.content{
    margin-top:1px;
    display: inline-block;  /* this is key */
    *display: inline;
    *zoom: 1;
    background:#fefefe;
}

注意：*display: inline;和*zoom: 1;是为 IE7 支持而添加的
