Question

我正在尝试使用@Keyframe CSS3创建一个漂亮的过渡，如果可能的话，使用jQuery来处理按钮的请求。

基本上，这个概念是“开始动画”时的概念。按钮被点击它必须为第1页到第2页的页面设置动画，与此视频完全相似： http://goo.gl/tkyLnS

这是我的HTML：

<main>
    <div class="cd-index cd-main-content">
        <div>
            <h1>Animated Page Transition</h1>

            <a class="cd-btn" href="about.html" data-type="page-transition">Start animation</a>
        </div>
    </div>
</main>

这里是我的CSS：

/ * --------------------------------

Primary style

-------------------------------- */
*, *::after, *::before {
  box-sizing: border-box;
}

html {
  font-size: 62.5%;
}

body {

  font-family: "Open Sans", sans-serif;
  color: #4089a6;
  background-color: #ffffff;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

a {
  color: #283040;
  text-decoration: none;
}

h1 {
  color: #ffffff;
  margin-bottom: 1em;
  font-size: 2.2rem;
}
@media only screen and (min-width: 768px) {
  h1 {
    font-size: 4.4rem;
    font-weight: 300;
  }
}

如果你可以帮助JSFIDDLE创建这个效果，看看我如何调整我的代码，这将是伟大的。对我来说真的很难过。希望有人可以帮助我JSFIDDLE：

不幸的是，你的JSFiddle似乎无法在我的浏览器中运行，这让我很难给出确切的答案。我确实观看了视频，并以一些代码为例。

＆＃13;

a {
    display: block;
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
    width: 300px;
    height: 300px;
    background-color: #0ff;
    transition: width 5s ease-out 1s, height 5s ease-out 1s, transform 1s ease-in-out 0s;
}

a:focus {
    width: 20px;
    height: 100px;
    transform: translate(-50%, -50%) rotate(90deg);
    transition-delay: 0s, 0s, 5s;
}
