Question

再次打电话给你帮助..

不确定这里发生了什么，我的导航翻转没有正确对齐，我已经检查了我的测量值，而且从我看到的不是那个。我正在使用Margin：0 auto将导航与页面中心对齐;我想知道这是不是问题？

我已经创建了一个小提琴http://jsfiddle.net/ca9rv/来理解我正在散布的内容（不确定为什么底部有一条蓝线 - 这在本地查看我的html页面时没有显示）。< / p>

<ul id="navigation">
    <li id="home"><a href="index.html">Home</a></li>
    <li id="promise"><a href="Our Promise">Our Promise</a></li>
    <li id="restaurants"><a href="Our Restaurants">Resume</a></li>
    <li id="contact"><a href="#">Contact</a></li>
</ul>

#navigation {
    background:url(http://img33.imageshack.us/img33/7388/navigationq.png) no-repeat;
    width: 940px;
    height: 50px;
    margin: 0 auto;
    padding: 0;
    margin-bottom:20px;
}

#navigation li, #navigation a {
    height: 50px;
    display: block;
}

#navigation li {
    float: left;
    list-style: none;
    display: inline;
    text-indent: -9999em;
}

#home { width: 103px; }
#promise { width: 176px; }
#restaurants { width: 206px; }
#contact { width: 151px; }

#home a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") 0px -50px no-repeat; }
#promise a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") -103px -50px no-repeat; }
#restaurants a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") -277px -50px no-repeat; }
#contact a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") -482px -50px no-repeat; }

Answer 1

更改 position value和width

就像这样

#home { width: 88px; }
#promise { width: 147px; }
#restaurants { width: 176px; }
#contact { width: 128px; }

#home a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") 0px -42px no-repeat; }
#promise a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") -91px -42px no-repeat; }
#restaurants a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") -236px -42px no-repeat; }
#contact a:hover { background:url("http://img33.imageshack.us/img33/7388/navigationq.png") -411px -42px no-repeat; }

首先，我认为你做错了。 1.停止使用背景图像，因为您希望它可以缩放。 2.快速浏览一下你所有宽度错误的CSS。为所有元素添加边框，您将会发生什么。 3.那里有蓝色边框，因为菜单上的高度高于背景图像。
