Question

所以我试图做一个＆＃34;演员＆＃34;我的一个作业部分，我希望演员的角色在演员盘旋时出现。我怎么做到这一点？当隐藏deadpool div的显示时，它在页面中留下了很大的空白。我希望在Ryan Reynolds徘徊之前不要显示它。

Answer 1

让我更偏离你现有的代码：

.cast * {
	box-sizing: border-box;
}

.cast {
	border-radius: 10px;
	background: #8b2323;
	font-family: Verdana, sans-serif;
	text-align: center;
	padding: 12px;
}

.cast img {
	border-radius: 50%;
	max-height: 300px;
}

.cast strong {
	background: white;
	display: block;
	border-radius: 10px;
	margin-top: 5px;
}

.cast .actor, 
.cast .role {
	width: 100%;
}

.cast .actor {
	display: block;
	z-index: 2;
}

.cast .role {
	display: none;
	z-index: 1;
}

.cast:hover .actor {
	display: none;
}

.cast:hover .role {
	display: block;
}

<article class="cast">
	<div class="actor">
      <img src="https://pbs.twimg.com/profile_images/741703039355064320/ClVbjlG-.jpg">
      <strong>Ryan Reynalds</strong>
	</div>
	
	<div class="role">
		<img src="http://cdn03.cdn.justjared.com/wp-content/uploads/headlines/2017/08/joi-harris-rip.jpg">
		<strong>Wade Wilson</strong>
	</div>
</article>

这减少了子元素的数量，并且（在我看来）使得选择哪个元素更容易显示/隐藏。您的目标是父包装器的:hover事件，而不是尝试使用ID（无法重复使用），而是定位.actor和.role。

一个问题是确保每个图像都是相同的维度，否则在更改时，如果框必须调整大小，则可能会出现一些没有吸引力的转换。

这可能是你想要做的吗？添加了：

article:hover .cast {
  display: none;
}

article:hover .cast2 {
  display: block;
}

＆＃13;

article {
  display: flex;
  flex-wrap: wrap;
  margin: auto;
  padding-top: 12px;
  padding-bottom: 12px;
  background-color: #8b2323;
  width: 48vw;
  min-height: 200px;
  min-width: 391px;
  font-family: verdana, sans-serif;
  justify-content: center;
}

article:hover .cast {
  display: none;
}

article:hover .cast2 {
  display: block;
}

.castcontainer {
  flex-wrap: wrap;
  min-width: 215px;
  width: 20%;
  height: 30%;
  overflow: hidden;
  padding: 5px;
}

#cast {
  border-radius: 50%;
  width: 100%;
}

.cast2 {
  display: none;
  text-align: center;
  background-color: #8b1a1a;
  border-radius: 10px;
  padding: 10px;
}

.cast:hover+.cast2 {
  display: block;
}

.cast {
  text-align: center;
  background-color: #8b1a1a;
  border-radius: 10px;
  padding: 10px;
}

p {
  background: white;
}

＆＃13;

<article>

  <div class="castcontainer" id="show1">
    <div class="cast">
      <img src="https://pbs.twimg.com/profile_images/741703039355064320/ClVbjlG-.jpg" class="castImg" id="CastImgRef">
      <p><b>Ryan Reynalds</b></p>
    </div>
  </div>

  <div class="castcontainer" id="show2">
    <div class="cast2">
      <img src="http://cdn03.cdn.justjared.com/wp-content/uploads/headlines/2017/08/joi-harris-rip.jpg" class="castImg">
      <p><b>Wade Wilson</b></p>
    </div>
  </div>

</article>

jQuery(function ($) {
    $('#show1').hover(function () {
        $(this).find('img').attr('src', function (i, src) {
            return src.replace('https://pbs.twimg.com/profile_images/741703039355064320/ClVbjlG-.jpg', 'http://cdn03.cdn.justjared.com/wp-content/uploads/headlines/2017/08/joi-harris-rip.jpg')
        })
        $('#textChange').text('Wade Wilson');
    }, function () {
        $(this).find('img').attr('src', function (i, src) {
            return src.replace('http://cdn03.cdn.justjared.com/wp-content/uploads/headlines/2017/08/joi-harris-rip.jpg', 'https://pbs.twimg.com/profile_images/741703039355064320/ClVbjlG-.jpg')
        })
        $('#textChange').text('Ryan Reynalds');
    })
})

添加thisjquery，它将正常工作

在class =＆＃34; cast＆＃34;中，内部div似乎是不必要的。和class =＆＃34; cast2＆＃34;。删除div并将该类添加到其父级。

当图像悬停时显示另一个div
