为什么 CSS 中的光标：指针效果不起作用

发布于08月26日

我将.about > span设为cursor: pointer，但当鼠标停留在<span>中的文本上时，光标不会变为指针模式.我想知道为什么它不起作用.

HTML:

 <div id="firstdiv">
      <div id="intro">
          <h1 id="name">YOU CHIA LAI</h1>
              <ul>
                  <li class="about">I am a Master of <span>Architecture</span>  
                   candidate at Rice University.  
                  </li>
                  <li class="about">I am also interested in <span>photography</span> &        
                  <span>web design</span>.</li>
                  <li class="about">I wish you can know more <span>about</span> me.
                  </li>
             </ul>
      </div>
  </div>

CSS:

#firstdiv {
    position:fixed;
    top:0;
    left:0;
    right:0;
    height:100%;
    width:100%;
    margin:auto;
    background:#E6E6E6;
    text-align:center;
    font-size:0;
    z-index:-2
}
.about > span {
    cursor:pointer;
    font-family:Eurofurence Light;
    padding:0 0 3px 0;
    color:#01DFA5;
}
