试图让以下似乎在桌面上工作的东西也能在移动设备上工作，但我看到的都是白色的。所以淡入永远不会发生。这是我的 HTML:
<a href="https://thecleverroot.com/meet-your-makers-hudson-valley-foie-gras/" title="Folio: Meet Your Makers" class="feature-link">
<section class="feature fade-in one" style="background: linear-gradient( rgba(0, 0, 0, 0.0), rgba(0, 0, 0, 0.35) ), url(https://thecleverroot.com/wp-content/uploads/header-hudson-valley-foie-gras.jpg ) no-repeat top center!important; background-size: cover!important;">
<section class="feature-caption"><p class="category-link">Growers</p><h2>Folio: Meet Your Makers </h2><p>Jenny Chamberlain, Chef of Product Development for Hudson Valley Foie Gras, Ferndale, NY</p><p class="read-more">Read</p></section></section>
</a>
这是 CSS:
.fade-in.one { -webkit-animation-delay: 1.25s; -moz-animation-delay: 1.25s; -o-animation-delay: 1.25s; animation-delay: 1.25s; }
.fade-in { opacity: 0; -webkit-animation: 1s ease-in 0s normal forwards 1 running fadeIn; -moz-animation: 1s ease-in 0s normal forwards 1 running fadeIn; -o-animation: 1s ease-in 0s normal forwards 1 running fadeIn; animation: 1s ease-in 0s normal forwards 1 running fadeIn; }
body.home a.feature-link { text-decoration: none; }
.feature-caption h2 { font-size: 64px; line-height: .75em; margin: .25em 0; }
.category-link {
background: #000;
border-radius: 14px;
display: inline-block;
margin: 0;
padding: 0 20px;
min-width: 90px;
height: 31px;
line-height: 31px;
color: #FFF;
font-size: 14px;
text-align: center;
font-weight: 400;
text-transform: uppercase;
}

我在 CodePen 上试过你的代码，但它在桌面上也不起作用(我在 Mac OS Yosemite 上测试了最新的 Chrome 和 Safari)。
如果您想在 HTML 页面加载后淡入淡出，您可以这样做:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.faded-out {
opacity: 0;
}
.fade-in {
opacity: 1;
transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-webkit-transition: opacity 1s ease-in-out;
}
#fadeInContainer {
background: url(https://thecleverroot.com/wp-content/uploads/header-hudson-valley-foie-gras.jpg);
padding: 60px;
}
</style>
<script type="text/javascript">
window.onload = function () {
document.getElementById("fadeInContainer1").className = "fade-in";
document.getElementById("fadeInContainer2").className = "fade-in"
}
</script>
</head>
<body>
<a href="https://thecleverroot.com/meet-your-makers-hudson-valley-foie-gras/" title="Folio: Meet Your Makers" class="feature-link">
<section id="fadeInContainer1" class="faded-out">
<h1>Content 1</h1>
</section>
<section id="fadeInContainer2" class="faded-out">
<h1>Content2</h1>
</section>
</a>
</body>
</html>
有 2 个 CSS 类:.faded-out(在加载页面时隐藏内容)和 fade-in(淡入内容)。
最初，内容具有 faded-out 类。加载页面后，我们将 CSS 类切换为 fade-in 以淡入内容。这是通过 javascript 完成的。
