html - CSS :target does not work on mozilla firefox

Question

我正在尝试在 css 上使用“:target”命令在我的 wordpress 网站上显示模式。它使用 chrome 浏览器工作正常，但如果我使用 mozilla，它就不起作用。当 whet ':target' 被激活时，我只需要将 'opacity' 属性更改为 1。 这是我正在使用的“css”:

    .modalDialog {
    position: fixed;
    font-family: Arial, Helvetica, sans-serif;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: rgba(0,0,0,0.8);
    z-index: 99999;
    opacity:0;
    -webkit-transition: opacity 400ms ease-in;
    -moz-transition: opacity 400ms ease-in;
    transition: opacity 400ms ease-in;
    pointer-events: none;
}



.modalDialog:target {
    opacity:1;
    pointer-events: auto;
}

感谢大家的帮助。

此示例适用于 mozilla firefox DEMO

HTML:

<ul>
    <li><a href="#h1">link 1</a></li>
    <li><a href="#h2">link 2</a></li>
  </ul>
  <h2 id="h1">link 1</h2>
   <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Libero eligendi, incidunt harum laborum ratione, labore quae modi hic est sint, aperiam corporis nesciunt dolor quasi iusto eaque itaque. Modi, deleniti.</p>
  <h2 id="h2">link 2</h2>
   <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Sint voluptates quia culpa, quos facilis, dicta reiciendis impedit deserunt a distinctio corporis in eos ipsum provident cum, dolorum dolorem tempore sapiente.</p>
</ul>

CSS:

h2:target {
    background: #fc0; /* Цвет фона */
    padding: 3px; 
}
