我一直以为替换< center>标签与< div style =“text-align：center;”>会得到相同的结果.显然我错了.
这是我的HTML的一部分：
(您也可以在我为此问题创建的页面中看到它的运行情况：
http://www.moviez.4pu.com/ErrorPageSO.aspx
<div style="margin: 0 auto; background-color:red;border:5px solid black;margin-top:5px;width:750px;text-align:center;">
<span style="width:560px;padding-right:10px;text-align:left;float:left;">
<h1>Oops... We're sorry.</h1>
<h3>You've just encountered an unknown error. <br /></h3>
This site is a work-in-progress,we have already been informed of the error and will do our best to fix it. <br />

<br />
<h3>
You can go back to the <a style="text-decoration:underline;" href="Default.aspx">Home page</a> and continue using Moviez.NET.
</h3>
</span><span style="width:180px;float:left;"><img src="Resources/Images/404.jpg" /></span>
</div>
我想做两件事：
>摆脱< center>标记,同时将div保持在页面的中心.
>确保外部DIV背景颜色和边框影响内跨距.
更新：
目标1完成.
目标#2的时间.
解决方法
使用保证金：0自动;封闭的< div>
<div style="margin: 0 auto; background-color:red;border:5px solid black;margin-top:5px;width:750px;text-align:center;"> <span style="width:560px;padding-right:10px;text-align:left;"> <h1>Oops...
