css - 如何创建通过点击触发的动画

Question

如何实现以下效果:当用户单击链接时，他会看到当前页面的内容缓慢向上移动，然后出现下一页的新内容。如果可能，我宁愿只使用 CSS。

Answer 1

可以通过过渡实现纯 CSS 解决方案。这是 the example 代码如下:

CSS

.message {
    background:#181818;
    color:#FFF;
    position: absolute;
    top: -250px;
    left: 0;
    width: 100%;
    height: 250px;
    padding: 20px;
    transition: top 300ms cubic-bezier(0.17, 0.04, 0.03, 0.94);
    overflow: hidden;
    box-sizing: border-box;

    }

.message h1 {
  color:#FFF;
}

#toggle {
  position:absolute;
  appearance:none;
  cursor:pointer;
  left:-100%;
  top:-100%;
}

#toggle + label {
  position:absolute;
  cursor:pointer;
  padding:10px;
  background: #26ae90;
width: 100px;
border-radius: 3px;
padding: 8px 10px;
color: #FFF;
line-height:20px;
font-size:12px;
text-align:center;
-webkit-font-smoothing: antialiased;
cursor: pointer;
  margin:20px 50px;
  transition:all 500ms ease;
}
#toggle + label:after {
  content:"Open" 
}

.container {
transition: margin 300ms cubic-bezier(0.17, 0.04, 0.03, 0.94);
  padding:5em 3em;
}

#toggle:checked ~ .message {
  top: 0;
}

#toggle:checked ~ .container {
  margin-top: 250px;
}

#toggle:checked + label {
  background:#dd6149;
}

#toggle:checked + label:after {
  content:"Close"
}

HTML

<input type="checkbox" name="toggle" id="toggle" />    
<label for="toggle"></label>      
<div class="container">
  <h1> Click the Open button to see hidden mesage.</h1>    
</div>
<div class="message">
  <h1> hello, I'm a hidden message. You found it.</h1>
</div>
