为什么标题导航会因更改浏览器大小而中断？怎么解决？我尝试了不同的方法，但我没有发现问题！我请求某人解释并解决问题。请帮忙。

如果您希望菜单不破，请设置固定宽度。
更新小提琴 - http://jsfiddle.net/begtw/6/
class es更改为id s（像div#content-area这样的元素每页都是唯一的，因此每页只使用一次id更有意义） id直接添加到徽标图片中。图像位于左侧HTML
<header>
<img src="imgs/logo.png" id="logo" alt="News Hour 24 logo" />
<nav id="nav-header">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">News</a></li>
<li><a href="#">Technology</a></li>
<li><a href="#">Health</a></li>
<li><a href="#">Sports</a></li>
<li><a href="#">Education</a></li>
<li><a href="#">Entertainment</a></li>
<li><a href="#">Support</a></li>
<li><a href="#">Sign Up</a></li>
</ul>
</nav>
</header>
CSS - 固定宽度。 #logo绝对定位。
nav#nav-header {
display:block;
padding:0;
font-size: 1em;
padding:0;
list-style-type:none;
margin: 15px 5px 10px 160px; /*Large left margin to fit #logo*/
height:50px;
float: left;
width: 1100px;
}
#logo{
position: absolute;
left: 10px; top: 10px;
}
这将修复您的菜单。对于较小的屏幕尺寸，您可能需要更多的灵活性，但是:)
