跨浏览器显示问题

Question

经过进一步调查，我发现我的 CSS 中有一些东西使我的导航显示很有趣 ->我的innerPage和下面的HTML（主页）上的所有内容都加载得很好，但我仍然被导航逼疯了，所以我上传了完整的html和css来解决这个问题，

HTML：

<div id="container"> 

<header> 
                <h1>company</h1> 
                <div id="logo"><a href="http://company.co.nz/">Home</a></div> 

<section id="sales"> 
        <p></p> 

</section> 

<section id="searchBox"> 

    <form id="searchBoxForm"> 
        <fieldset> 
                <input type="text" name="search" id="search" placeholder="Search Here" /> 
                <input class="submit" type="submit" name="submit" id="submit" value="Search" /> 
        </fieldset> 

    </form>

好吧，我没有确切地看到你所看到的，但我确实看到 FF 中有点混乱。我对你的几个 CSS 语句做了一些更改，它在 Chrome 和 FF 中工作。这是我所做的：

1. 更改了“#mainMenu ul li”删除了“display：inline;”添加了“浮动：左；列表样式：无；”

   #mainMenu ul li
   {
       左边距：0px；
       宽度：120px；
       高度：56px；            
       职位：亲属；
       浮动：向左；
       列表样式：无；
   }
   

2. 添加了“#mainMenu .signup”和“float: right;”

   #mainMenu .signup
   {
       浮动：右；
   }
   

3. 删除了“margin-left: 360px;”来自“#mainMenu .signup a”

   #mainMenu .signup a
   {
       背景颜色：#69c21c；
       高度：50px；
      -webkit-边框-右上半径：2px；
      -webkit-border-bottom-right-radius:2px;
      -moz-边框-半径-topright：2px；
      -moz-边框-半径-bottomright：2px；
   }
   

现在，由于我在导航栏中使用了浮动，您可能需要在结束导航标记后放置一个清晰的 div，以清除浮动并正常启动一个新的 div。

<div style="clear: both;"> </div>
