一个锚标签不起作用，类似的锚标签起作用

Question

我有一个<li>元素，带有3个非常相似的锚标记。 前两个可以正常工作，但第三个则不能： hover时确实会改变其颜色，但不可单击。 对于Google Chrome，Firefox和IE11，此行为类似，因此可能不是浏览器。 我有很多类似的页面，以前从未遇到过此类麻烦。

LIVE页面在这里 ， CTRL + End使您进入最终注释，其中最后一个<a>是问题。

本节的基础HTML是

 <ul id='commentul'> <li> <img alt='' src='http://1.gravatar.com/avatar/72f74d7bd6a20a2f9dd37e6af9d45850?s=80&#038;d=mm&#038;r=g' srcset='http://1.gravatar.com/avatar/72f74d7bd6a20a2f9dd37e6af9d45850?s=160&amp;d=mm&amp;r=g 2x' class='avatar avatar-80 photo' height='80' width='80' /> <h3>By Eszter Babarczy on July 30th, 2016</h3> <p>Hi! I ran the dialogue with 21 variables using their names. The program insists these are string variables (although they are set to scale). What am I doing wrong?

SPSS will (rightfully) refuse to generate descriptives for string variables and throw a warning.</p> <p>Now, in SPSS, you can have string variables set to scale. It doesn't make sense, though. "Scale" in SPSS means that you're dealing with a metric variable (the <a href="http://www.spss-tutorials.com/measurement-levels/">measurement level</a> is interval or ratio). </p> <p>The defining characteristic of metric variables is that numeric calculations (sum, mean) are meaningful for them and such calculations are not possible on string variables. So we usually see that "scale" is only used for numeric variables whereas all string variables are set to nominal but perhaps this doesn't hold for your data.</p> <p>A tiny example illustrating this point is <a href="http://www.spss-tutorials.com/spss-syntax-examples/no-descriptives-for-metric-string-variable.html">No Descriptives for Metric String Variable</a>. If that doesn't hold for your data, please get back at me, ok?</p> </li><!-- #comment-## --> </ul><!-- id='commentul'> -->

在最后一个锚点中a您有一个  在标签内，如下所示： <a &nbsp;href="..."
