Question

我想知道是否有人可以解释为什么每栏中我的“内容”类以下的内容都会消失？我希望它能使活动列中的所有内容都可见（在某种程度上有效）并且非活动列中的所有内容都会消失。

这是HTML：

 <div id="container">
    <div id="header-bar">
        <ul>
            <li>
                <a href="gallery.html">Gallery</a>
            </li>
            <li>
                <p>| Dare.me |</p>
            </li>
            <li>
                <a href="leaderboard.html">Leaderboard</a>
            </li>
        </ul>
    </div><!--header-bar-->

    <div class="columns">
        <div id="left-column">
            <p class="title left">Easy</p>
            <p class="content">Feeling like a whimp?<br/> 
            Take one of our easy dares.</p>

            <div class="circle-text"><div><a href="php/easy.php">Click <span class="bold">Here</span> For An Easy Dare</a></div></div>

            <div id="test"><p>Test Text</p></div>

        </div><!--left-column-->

        <div id="centre-column">
            <p class="title centre">Medium</p>
            <p class="content">Feeling adventurous<br /> 
            are we?</p>

            <div class="circle-text"><div><a href="php/medium.php">Click <span class="bold">Here</span> For A Medium Dare</a></div></div>

        </div><!--centre-column--> 

        <div id="right-column">
            <p class="title right">Hard</p>
            <p class="content">Feeling lucky?<br />
            prepare yourself!</p>

            <div class="circle-text"><div><a href="php/hard.php">Click <span class="bold">Here</span> For A Hard Dare</a></div></div>

        </div><!--right-column-->
    </div><!--columns-->
 </div><!--container-->

Answer 1

因为当你写...

.columns:hover div{  
  transition: opacity linear .2s;    
  opacity:0.3;
}

...你的说法会在<div>的孩子{/ 1}}中逐渐消失。

您可能想要直接子CSS选择器：

.columns

为什么活动列上的“内容”类下面的任何内容都会消失？
