我为我的网站的中间导航栏构建了一个 CSS 精灵。在所有其他浏览器中，它都能正确显示 - 全部整齐划一。但是，在 Firefox 中，最终按钮/链接的显示比栏的其余部分略低，我不知道为什么。

这是我正在使用的代码：

<div id="midnavbar">
<ul id="midnav">
<li id="midnav-1"><a href="http://127.0.0.1:4001/wordpress/?page_id=13"    title="Community Connections">Community Connections</a></li>
<li id="midnav-2"><a href="http://127.0.0.1:4001/wordpress/?page_id=18 " title="Community Living">Community Living</a></li>
<li id="midnav-3"><a href="http://127.0.0.1:4001/wordpress/?page_id=118" title="Autism Spectrum">Autism Spectrum</a></li>
<li id="midnav-4"><a href="http://127.0.0.1:4001/wordpress/?page_id=123" title="Positive Support">Positive Support</a></li>
<li id="midnav-5"><a href="http://127.0.0.1:4001/wordpress/?page_id=121" title="Medically Fragile">Medically Fragile</a></li>
</ul>
</div>

CSS：

#midnavbar {
display:block;
}

ul#midnav {
width:955px;
height:48px;
list-style:none;
overflow:hidden;
}

ul#midnav li {
display:inline;
list-style:none;
}

ul#midnav li a {
height:48px;
float:left;
text-indent: 100%;
white-space: nowrap;
overflow: hidden;
}
ul#midnav li#midnav-1 a {
width:223px;
background: transparent url("http://127.0.0.1:4001/wordpress/wp-    content/themes/thoriumific/images/midnav.jpg") no-repeat 0 0; /* X and Y position at 0 */
}
ul#midnav  li#midnav-1 a:hover {
background-position:0 -48px; /* Y position -45px for Over instance image */
}
ul#midnav li#midnav-2 a {
width:178px;
background: transparent url("http://127.0.0.1:4001/wordpress/wp-   content/themes/thoriumific/images/midnav.jpg") no-repeat -223px 0;
}
ul#midnav  li#midnav-2 a:hover {
background-position:-223px -48px;
}
ul#midnav li#midnav-3 a {
width:179px;
background: transparent url("http://127.0.0.1:4001/wordpress/wp-content/themes/thoriumific/images/midnav.jpg") no-repeat -401px 0;
}
ul#midnav  li#midnav-3 a:hover {
background-position:-401px -48px;
}
ul#midnav li#midnav-4 a {
width:186px;
background: transparent url("http://127.0.0.1:4001/wordpress/wp-content/themes/thoriumific/images/midnav.jpg") no-repeat -580px 0;
}
ul#midnav  li#midnav-4 a:hover {
background-position:-580px -48px;
}
ul#midnav li#midnav-5 a {
width:189px;
background: transparent url("http://127.0.0.1:4001/wordpress/wp-content/themes/thoriumific/images/midnav.jpg") no-repeat -766px 0;
}
ul#midnav  li#midnav-5 a:hover {
background-position:-766px -48px;
}

我不确定我做错了什么，所以我不知道如何解决它。任何建议将不胜感激！

You should avoid using display: inline; because it's buggy, and as you've figured it out it doesn't really work the same in all browsers. I suggest you use float: left; Also I cleaned up your css a bit.

#midnav {
    width: 955px;
    height: 48px;
    list-style: none;
    overflow: hidden;
}

#midnav li {
    float: left;
}

#midnav a {
    height: 48px;
    display: block;
    text-indent: 100%;
    white-space: nowrap;
    overflow: hidden;
}


#midnav-1 a {
    width: 223px;
    background: transparent url("http://127.0.0.1:4001/wordpress/wp-    content/themes/thoriumific/images/midnav.jpg") no-repeat 0 0; /* X and Y position at 0 */
}

#midnav-1 a:hover { background-position:0 -48px }

#midnav-2 a {
    width:178px;
    background: transparent url("http://127.0.0.1:4001/wordpress/wp-   content/themes/thoriumific/images/midnav.jpg") no-repeat -223px 0;
}

#midnav-2 a:hover { background-position:-223px -48px }

#midnav-3 a {
    width:179px;
    background: transparent url("http://127.0.0.1:4001/wordpress/wp-content/themes/thoriumific/images/midnav.jpg") no-repeat -401px 0;
}

#midnav-3 a:hover { background-position:-401px -48px }

#midnav-4 a {
    width:186px;
    background: transparent url("http://127.0.0.1:4001/wordpress/wp-content/themes/thoriumific/images/midnav.jpg") no-repeat -580px 0;
}

#midnav-4 a:hover { background-position:-580px -48px }

#midnav-5 a {
    width:189px;
    background: transparent url("http://127.0.0.1:4001/wordpress/wp-content/themes/thoriumific/images/midnav.jpg") no-repeat -766px 0;
}

#midnav-5 a:hover { background-position:-766px -48px }​
