Firefox的問題：在帶有顯示項的表中絕對位置

Question

我有3個li，試圖將它們水平對齊，然后在每個li內放置一個跨度。

這些跨度在Chrome中的位置正確，但在Firefox的li邊界之外。

有人可以幫忙嗎？

<div id="blank-slate-steps">
   <ul>
      <li class="first">
         <h3><em>Step 1</em>Create Something</h3>
         <p>Once you have created Something Else you can Create Final Thing</p>
         <span></span>
      </li>
      <li class="second">
         <h3><em>Step 2</em>Create Something Else</h3>
         <p>Once you have created Something Else you can Create Final Thing</p>
         <span></span>
      </li>
      <li class="third">
         <h3><em>Step 3</em>Create Final Thing</h3>
         <p>Once you have created Something Else you can Create Final Thing</p>

Answer 1

使用相對位置作為空白面板步驟div。

#blank-slate-steps {
    background-color: #E8E8E8;
    bottom: 0;
    font-family: OpenSansCondensedBold,sans-serif;
    text-align: center;
    width: 100%;
    position: relative;
}

Answer 2

好的，我已經使它起作用了，您可以這樣操作： 小提琴

說明：我所做的是，我使用的是position: relative; #blank-slate-steps和使用position: relative; 再次為div並將<li>內容包裝在其中

的HTML

<div id="blank-slate-steps">
   <ul>
      <li class="first">
          <div style="position: relative;">
         <h3><em>Step 1</em>Create Something</h3>
         <p>Once you have created Something Else you can Create Final Thing</p>
         <span></span>
          </div>
      </li>
      <li class="second">
          <div style="position: relative;">
         <h3><em>Step 2</em>Create Something Else</h3>
         <p>Once you have created Something Else you can Create Final Thing</p>
         <span></span>
           </div>
      </li>
      <li class="third">
          <div style="position: relative;">
         <h3><em>Step 3</em>Create Final Thing</h3>
         <p>Once you have created Something Else you can Create Final Thing</p>
         <span></span>
          </div>
      </li>
   </ul>
</div>

的CSS

body{
    padding-top: 300px;
}
#blank-slate-steps {
    background-color: #E8E8E8;
    bottom: 0;
    font-family: OpenSansCondensedBold,sans-serif;
    text-align: center;
    width: 100%;
    position: relative;
}
#blank-slate-steps li {
    display: table-cell;
    max-width: 300px;
    padding: 40px;
    width: 300px;
}
#blank-slate-steps h3 {
    font-size: 1.6em;
    margin-bottom: 0.6em;
}
#blank-slate-steps h3 em {
    color: #878787;
    float: left;
    font-size: 0.8em;
    font-style: normal;
    margin-bottom: 4px;
    text-transform: uppercase;
    width: 100%;
}
#blank-slate-steps li.second span {
    background: red url("../images/sprite/icons-grey-38.png") no-repeat scroll 0 -56px transparent;
    height: 37px;
    width: 36px;
}
#blank-slate-steps span {
    background-color: red;
    display: block;
    height: 20px;
    left: -10px;
    position: absolute;
    top: 50px;
    width: 20px;
}

Answer 3

嘗試像這樣先將您的跨度放在首位：

<li class="second">
     <span></span>
     <h3><em>Step 2</em>Create Something Else</h3>
     <p>Once you have created Something Else you can Create Final Thing</p>
  </li>

並將跨度放在position:relative和float:left
