如何在悬停时显示图像上的文本？

Question

如何在悬停时显示图像上的文本？

87

我想在鼠标悬停在图像上时显示其描述。我已经使用图像精灵和悬停来完成了不太理想的方式，如下所示：我希望它看起来与我所拥有的完全相同，但是使用真实文本而不是图像。

我尝试了几种不同的方法，但似乎无法弄清楚如何做到这一点。我正在尝试仅使用HTML和CSS来完成，但我不确定是否可能。

请随意查看我的代码，我将在此处粘贴我认为相关的部分。 HTML

div#projectlist {
  width: 770px;
  margin: 0 auto;
  margin-top: 20px;
  margin-bottom: 40px;
}

div#buzzbutton {
  display: block;
  float: left;
  margin: 2px;
  background: url(content/assets/thumbnails/design/buzz_sprite.jpg) 0 0px no-repeat;
  width: 150px;
  height: 150px;
}

div#buzzbutton:hover {
  background: url(content/assets/thumbnails/design/buzz_sprite.jpg);
  width: 150px;
  height: 150px;
  background-position: 0 -150px;
}

div#slinksterbutton {
  display: block;
  float: left;
  background: url(content/assets/thumbnails/design/slinkster_sprite.jpg) 0 0px no-repeat;
  width: 150px;
  height: 150px;
  margin: 2px;
}

div#slinksterbutton:hover {
  background: url(content/assets/thumbnails/design/slinkster_sprite.jpg);
  width: 150px;
  height: 150px;
  background-position: 0 -150px;
}

<div id="projectlist">
  <div id="buzzbutton">
    <a href="buzz.html" title=""><img src="content/assets/thumbnails/transparent_150x150.png" alt="" /></a>
  </div>

  <div id="slinksterbutton">
    <a href="slinkster.html" title=""><img src="content/assets/thumbnails/transparent_150x150.png" alt="" /></a>
  </div>
</div>

请注意，文本并非100%可控。即使使用您正在使用的样式，它看起来都适合图像的尺寸，但如果用户指定更大的字体大小，则可能会出现溢出和/或隐藏文本的情况。 - cimmanon

如果你正在使用Bootstrap，那么很有可能你会用到一个很好的功能叫做“tooltip”，它可以完全实现你所描述的功能。 - Robert Sinclair

在您的HTML中，尝试将要出现在代码标题部分的文本放置在其中：

<a  href="buzz.html" title="buzz hover text">

您也可以对图像的alt文字执行相同的操作。

这是最简单的解决方案，但不幸的是，文本只会在一秒钟后出现。 - George

顺便说一句，如果您不想使用 <a href="..."> (例如，鼠标光标更改、在Chrome底部显示的网址、单击后执行的操作和URL更改) </a> 所有附带的行为，则可以使用不带 href 的 <a> 标签：<a title="title"><img src="..."/>}。 - Mark

我已经寻找这个东西好几年了，其实并不是很积极，但我一直在想@mrpopo。 - ScottC

您也可以在图像标签中使用title属性。

<img src="content/assets/thumbnails/transparent_150x150.png" alt="" title="hover text" />

这是我用来实现鼠标悬停时文字出现的方法：

* {
  box-sizing: border-box
}

div {
  position: relative;
  top: 0px;
  left: 0px;
  width: 400px;
  height: 400px;
  border-radius: 50%;
  overflow: hidden;
  text-align: center
}

img {
  width: 400px;
  height: 400px;
  position: absolute;
  border-radius: 50%
}

img:hover {
  opacity: 0;
  transition:opacity 2s;
}

heading {
  line-height: 40px;
  font-weight: bold;
  font-family: "Trebuchet MS";
  text-align: center;
  position: absolute;
  display: block
}

div p {
  z-index: -1;
  width: 420px;
  line-height: 20px;
  display: inline-block;
  padding: 200px 0px;
  vertical-align: middle;
  font-family: "Trebuchet MS";
  height: 450px
}

我看到很多人使用图像标签。我更喜欢使用背景图像，因为我可以操纵它。例如，我可以：

添加更平滑的过渡效果
通过使用“background-size: cover;”属性，节省剪裁图像的时间。

HTML/CSS代码：

.overlay-box {
  background-color: #f5f5f5;
  height: 100%;
  background-repeat: no-repeat;
  background-size: cover;
}

.overlay-box:hover .desc,
.overlay-box:focus .desc {
  opacity: 1;
}

/* opacity 0.01 for accessibility */
/* adjust the styles like height,padding to match your design*/
.overlay-box .desc {
  opacity: 0.01;
  min-height: 355px;
  font-size: 1rem;
  height: 100%;
  padding: 30px 25px 20px;
  transition: all 0.3s ease;
  background: rgba(0, 0, 0, 0.7);
  color: #fff;
}

<div class="overlay-box" style="background-image: url('https://via.placeholder.com/768x768');">
  <div class="desc">
    <p>Place your text here</p>
    <ul>
      <li>lorem ipsum dolor</li>
      <li>lorem lipsum</li>
      <li>lorem</li>
    </ul>
  </div>
</div>

为了提高可访问性，您应该使用正确的语义标签。使用figure作为容器，并将文本包含在图像中的figcaption中。

将position: relative应用于容器，然后将position: absolute应用于figcaption。通过使用display: block隐藏figcaption，并通过在包装的figure元素上使用:hover使其再次可见。

figure {
  position: relative;
}

figcaption {
  position: absolute;
  inset: 2px;  
  display: none;
}

figure:hover figcaption {
  display: flex;
}


/* for visualization only */
figure {
  display: inline-block;
}

figcaption {
  padding: 1em;
  justify-content: center;
  align-items: center;
  background-color: rgba(255, 255, 255, 0.7);
}

img {
  border: 2px dashed red;
}

<figure>
  <img src="https://via.placeholder.com/200.jpg" alt="placeholder image used for demonstration">
  <figcaption>placeholder image used for demonstration</figcaption>
</figure>

很简单。将图片和“鼠标悬停时出现”的描述包裹在一个具有相同尺寸的div中。然后，使用一些CSS，使描述在悬停该div时出现。

/* quick reset */
* {
  margin: 0;
  padding: 0;
  border: 0;
}

/* relevant styles */
.img__wrap {
  position: relative;
  height: 200px;
  width: 257px;
}

.img__description {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(29, 106, 154, 0.72);
  color: #fff;
  visibility: hidden;
  opacity: 0;

  /* transition effect. not necessary */
  transition: opacity .2s, visibility .2s;
}

.img__wrap:hover .img__description {
  visibility: visible;
  opacity: 1;
}

<div class="img__wrap">
  <img class="img__img" src="http://placehold.it/257x200.jpg" />
  <p class="img__description">This image looks super neat.</p>
</div>

一个好用的小工具: https://jsfiddle.net/govdqd8y/

编辑:

如果您不想显式设置包裹 <div> 中的 <img> 的高度，还有另一种选择，那就是将 <div> 的显示设置为 inline-block。（请记住，如果图像加载失败，它看起来不会很好。）

如果您选择此选项，则会注意到 <img> 与包装 <div> 底部之间会留下轻微的间隔。这是因为 <img> 的默认 vertical-align 值为 baseline。如果将其设置为 bottom，则它将消失。

这里有一个使用此选项的演示：https://jsfiddle.net/joplomacedo/5cL31o0g/
