我想制作一个加载屏幕和一个淡入淡出的页面，如下所示：https : //www.w3schools.com/howto/tryit.asp?filename=tryhow_css_loader5。问题是我不知道如何结束加载循环并使其褪色。代码 <body> <div class="sk-chase"> <div class="sk-chase-dot"></div> <div class="sk-chase-dot"></div> <div class="sk-chase-dot"></div> <div class="sk-chase-dot"></div> <div class="sk-chase-dot"></div> <div class="sk-chase-dot"></div> </div> </body>body { background-color: #636e72; }sk-chase { width: 40px; height: 40px; animation: sk-chase 2.5s infinite linear both; display: flex; justify-content: center; align-items: center; margin: 0 auto; top: 50%; left: 50%; position: absolute; } .sk-chase-dot { width: 100%; height: 100%; position: absolute; left: 0; top: 0; animation: sk-chase-dot 2.0s infinite ease-in-out both; }.sk-chase-dot:before { content: ''; display: block; width: 25%; height: 25%; background-color: #fff; border-radius: 100%; animation: sk-chase-dot-before 2.0s infinite ease-in-out both; @keyframes sk-chase { 100% { transform: rotate(360deg); } } @keyframes sk-chase-dot { 80%, 100% { transform: rotate(360deg); } } @keyframes sk-chase-dot-before { 50% { transform: scale(0.4); } 100%, 0% { transform: scale(1.0); } }

animation: sk-chase 2.5s infinite linear both;
Wordinfinite是你的问题。改为使用多个代表infinite。在你的情况下是1。

您需要 JavaScript 来告诉浏览器何时隐藏加载程序并显示内容。见下面的片段
var myVar;
function myFunction() {
myVar = setTimeout(showPage, 3000);
}
function showPage() {
document.querySelector("#loader").style.display = "none";
document.querySelector("#myDiv").style.display = "block";
document.querySelector("body").style.backgroundColor = "white";
}
body {
background-color: #636e72;
}
.sk-chase {
width: 40px;
height: 40px;
animation: sk-chase 2.5s infinite linear both;
display: flex;
justify-content: center;
align-items: center;
margin: 0 auto;
top: calc(50% - 20px);
left: calc(50% - 20px);
position: absolute;
}
.sk-chase-dot {
width: 100%;
height: 100%;
position: absolute;
left: 0;
top: 0;
animation: sk-chase-dot 2.0s infinite ease-in-out both;
}
.sk-chase-dot:before {
content: '';
display: block;
width: 25%;
height: 25%;
background-color: #fff;
border-radius: 100%;
animation: sk-chase-dot-before 2.0s infinite ease-in-out both;
}
.sk-chase-dot:nth-child(1) {
animation-delay: -1.1s;
}
.sk-chase-dot:nth-child(2) {
animation-delay: -1.0s;
}
.sk-chase-dot:nth-child(3) {
animation-delay: -0.9s;
}
.sk-chase-dot:nth-child(4) {
animation-delay: -0.8s;
}
.sk-chase-dot:nth-child(5) {
animation-delay: -0.7s;
}
.sk-chase-dot:nth-child(6) {
animation-delay: -0.6s;
}
.sk-chase-dot:nth-child(1):before {
animation-delay: -1.1s;
}
.sk-chase-dot:nth-child(2):before {
animation-delay: -1.0s;
}
.sk-chase-dot:nth-child(3):before {
animation-delay: -0.9s;
}
.sk-chase-dot:nth-child(4):before {
animation-delay: -0.8s;
}
.sk-chase-dot:nth-child(5):before {
animation-delay: -0.7s;
}
.sk-chase-dot:nth-child(6):before {
animation-delay: -0.6s;
}
@keyframes sk-chase {
100% {
transform: rotate(360deg);
}
}
@keyframes sk-chase-dot {
80%,
100% {
transform: rotate(360deg);
}
}
@keyframes sk-chase-dot-before {
50% {
transform: scale(0.4);
}
100%,
0% {
transform: scale(1.0);
}
}
<body onload="myFunction()">
<div id="loader" class="sk-chase">
<div class="sk-chase-dot"></div>
<div class="sk-chase-dot"></div>
<div class="sk-chase-dot"></div>

<div style="display:none;" id="myDiv" class="animate-bottom">
<h2>Tada!</h2>
<p>Some text in my newly loaded page..</p>
