html - 将后退箭头与下拉菜单对齐的问题

Question

下拉菜单旁边的后退箭头间距有问题。问题是它使箭头居中，就好像下拉菜单处于事件状态一样。我希望它位于下拉菜单的左侧而不是对齐方式。

我包含了一个 jsfiddle show 显示。

HTML

<div id="portfolio">
 <table>
 <tr>
 <td>
    <a href="index.html"><div class="back-arrow-left" ></div></a>
 </td>
 <td>
 <dropdown>
    <input id="toggle2" type="checkbox">
    <label for="toggle2" class="animate">Portfolio<i class="fa fa-list float-right"></i></label>
    <ul class="animate">
       <li class="animate">Websites</li>
       <li class="animate">Computer Animations</li>
       <li class="animate">C/C++ Programs</li>
    </ul>
 </dropdown>
 </td>
 </tr>
 </table>
 </div>

CSS

  &:hover {

    color: white;
    .fa{

    }
  }
  }
 }

您使用该表是否有特殊原因？这不符合 HTML 5 标准，以后可能会导致问题。

事实上，是导致您出现问题的表格。您有围绕数据的表格，应该将其定向到您想要的顺序，但您已经在使用 css 将其与表格对齐!

如果您取出表格并在您的 css 中添加一行，它会完美地工作。

.back-arrow-left {
       float: left;
       width: 0;
       height: 0;
       border-top: 30px solid transparent;
       border-bottom: 30px solid transparent;
       border-right:30px solid gray;
       vertical-align: top;
}

<div id="portfolio">
    <a href="index.html"><div class="back-arrow-left" ></div></a>
    <dropdown>
      <input id="toggle2" type="checkbox">
      <label for="toggle2" class="animate">Portfolio<i class="fa fa-list float-right"></i></label>
         <ul class="animate">
           <li class="animate">Websites</li>
           <li class="animate">Computer Animations</li>
         <li class="animate">C/C++ Programs</li>
      </ul>
   </dropdown>
 </div>
