我正在尝试在 this article from CSS-tricks 之后的 Logo 上创建悬停状态，但我无法让它发挥作用。

我使用的是 WordPress 主题，我只能在其中编辑 CSS(和 JS，但我对此一无所知)。

CSS 技巧代码:

HTML

<head>
  <title>Really Cool Page</title>
</head>
<body>
  <!-- .header would be across site on other pages with different children, so no background image adding -->
  <div class="header">
    <img class="banner" src="//notrealdomain1.com/banner.png">
  </div>
</body>

CSS

/* All in one selector */
.banner {
  display: block;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  background: url(http://notrealdomain2.com/newbanner.png) no-repeat;
  width: 180px; /* Width of new image */
  height: 236px; /* Height of new image */
  padding-left: 180px; /* Equal to width of new image */
}

Website I'm working on

我的额外 CSS

.logo:hover img {
    display: block;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    background: url(http://couill.art/wp-content/uploads/2018/05/logo-Couillart.gif) no-repeat;
    width: 50px; /* Width of new image */
    height: 50px; /* Height of new image */
    padding-left: 50px; /* Equal to width of new image */
}

我尝试使用这些设置，但我的想法已经用完了。

最佳答案

尝试修改行:.logo:hover img {到 .banner:hover {
我还建议使用背景大小属性来修改背景图片的大小，以便元素保持其初始大小。 (否则只有当您将鼠标悬停在图像的左上角区域时它才会起作用。

/* All in one selector */
.banner {
  display: block;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  background: url(http://www.picture-newsletter.com/arctic/arctic-06_small.jpg) no-repeat;
  width: 180px; /* Width of new image */
  height: 236px; /* Height of new image */
  padding-left: 180px; /* Equal to width of new image */
  background-size: 100% 100%; 
}

.banner:hover {
    display: block;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    background: url(http://www.picture-newsletter.com/arctic/arctic-02_small.jpg) no-repeat;

<head>
  <title>Really Cool Page</title>
</head>
<body>
  <!-- .header would be across site on other pages with different children, so no background image adding -->
  <div class="header">
    <img class="banner" src="http://www.picture-newsletter.com/arctic/arctic-03_small.jpg">
  </div>
</body>

对于您提供的代码段，您需要包含 background-size: 100%, 100%;

.logo img, .logo {
  width: 50px;
  /* Width of new image */
  height: 50px;
}


.logo:hover img {
  display: block;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  background: url(http://couill.art/wp-content/uploads/2018/05/logo-Couillart.gif) no-repeat;
  width: 50px;
  /* Width of new image */
  height: 50px;
  /* Height of new image */
  padding-left: 50px;
  /* Equal to width of new image */
  background-size: 100%, 100%;
}
<div class="logo navbar-left">
    <a href="http://couill.art" title="Couillard">
        <img src="http://couill.art/wp-content/uploads/2018/05/logo-Couillart-gif.png" alt="logo">
    </a>
</div>
