css - h2 跨度之间的虚线

Question

我一直在尝试在我的网站上添加一些虚线。
我开始理解这个想法，但我遇到了另一个问题......
我正在制作另一条虚线，这次是在文本和图像之间。这个有点不同。

我也遇到了一些问题，有时由于宽度的变化图像会出现在线条下面:当我更新我的网站时，等等。

我怎样才能把虚线的宽度改成h2的总宽度？
我希望虚线不会打扰任何东西，只是顺利穿过它。

这是我正在使用的代码，我需要在基本原则中保持它:

      <script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
      <script type="text/javascript">
      $(document).ready(function(){

      $('.serviceDesc').hide();
      $('.serviceName:first').addClass('active').next().show(); 

      $('.serviceName').click(function(){
      if( $(this).next().is(':hidden') ) { 
      $('.serviceName').removeClass('active').next().slideUp(); 
      $(this).toggleClass('active').next().slideDown(); 
      }
      return false; 
      });

      });
      </script>
      <style>
      #servicesContainer {
          width: 485px;
          height: 400px;
          margin: 0 auto;
          margin-top: 20px;
      }
      h2.serviceName {
          margin: 0;
          margin-bottom: 5px;
          margin-top: 5px;
          background-image: url(http://i.imgur.com/IcnZl.png);
          background-position: right top;
          background-repeat:no-repeat;
          height: 29px;
          line-height: 24px;
          width: 480px;
          font-size: 18px;
          font-weight: bold;
          float: left;
          color:#000;
      }
      h2.serviceName a {
          color: #000;
          text-decoration: none;
          display: block;
      }
      h2.active {
          background-position: right bottom;
      }
      .serviceDesc {
          margin: 0 0 10px;
          padding: 0;
          overflow: hidden;
          width: 480px;
          clear: both;
      }
      .serviceDesc .block {
      }
      .serviceDesc .block p {
          color: #413f44;
          margin: 0;
          font-size:18px;
      }
      </style>

Answer 1

与 phone/email question 一样，都是一样的道理。您可以在元素上使用背景图像来创建虚线。由于您已经了解了 <h2> 的背景知识，将其添加到 <a> :

h2.serviceName a {
    background: url(dots.gif) repeat-x bottom left;
    /* Other CSS styles */
}

这是 an example .作为奖励，这意味着您也可以摆脱所有硬编码点。

更新:如果你想屏蔽单词后面的点，添加一个 <span>具有环绕文本的纯色背景的元素:

HTML

<h2>
    <a href="">
        <span>Juicy text</span>
    </a>
</h2>

CSS

a span {
    background-color: #fff;
}

这将防止 <a> 的虚线背景从显示通过。
