CSS 3 从左侧过渡滑入

Answer 1

您可以使用 CSS3 过渡或 CSS3 动画在元素中滑动。

浏览器支持：http://caniuse.com/

我做了两个简单的例子只是为了向你展示我的意思。

CSS 过渡（悬停时）

演示一

相关代码

.wrapper:hover #slide {
    transition: 1s;
    left: 0;
}

在本例中，我只是用 1 秒将位置从

left: -100px;

转换为

0;

。期间。也可以使用

transform: translate();

移动元素

CSS动画

演示二

#slide {
    position: absolute;
    left: -100px;
    width: 100px;
    height: 100px;
    background: blue;
    -webkit-animation: slide 0.5s forwards;
    -webkit-animation-delay: 2s;
    animation: slide 0.5s forwards;
    animation-delay: 2s;
}

@-webkit-keyframes slide {
    100% { left: 0; }
}

@keyframes slide {
    100% { left: 0; }
}

与上面（演示一）原理相同，但动画在 2s 后自动开始，在本例中，我将

animation-fill-mode

设置为

forwards

，这将保持结束状态，使动画结束时保持 div 可见.

就像我说的，有两个简单的例子来向您展示如何做到这一点。

Answer 2

使用 CSS3 2D

transform

避免性能问题（移动设备）

一个常见的陷阱是对 left

/

top

/

right

/

bottom

属性进行动画处理，而不是使用 

css-transform 来实现相同的效果。由于各种原因，转换的语义使它们更容易卸载，但是 left

/

top

/

right

/

bottom

 则要困难得多。

演示：

var $slider = document.getElementById('slider');
var $toggle = document.getElementById('toggle');

$toggle.addEventListener('click', function() {
    var isOpen = $slider.classList.contains('slide-in');

    $slider.setAttribute('class', isOpen ? 'slide-out' : 'slide-in');
});

#slider {
    position: absolute;
    width: 100px;
    height: 100px;
    background: blue;
    transform: translateX(-100%);
    -webkit-transform: translateX(-100%);
}

.slide-in {
    animation: slide-in 0.5s forwards;
    -webkit-animation: slide-in 0.5s forwards;
}

.slide-out {
    animation: slide-out 0.5s forwards;
    -webkit-animation: slide-out 0.5s forwards;
}
    
@keyframes slide-in {
    100% { transform: translateX(0%); }
}

@-webkit-keyframes slide-in {
    100% { -webkit-transform: translateX(0%); }
}
    
@keyframes slide-out {
    0% { transform: translateX(0%); }
    100% { transform: translateX(-100%); }
}

@-webkit-keyframes slide-out {
    0% { -webkit-transform: translateX(0%); }
    100% { -webkit-transform: translateX(-100%); }
}

<div id="slider" class="slide-in">
    <ul>
        <li>Lorem</li>
        <li>Ipsum</li>
        <li>Dolor</li>
    </ul>
</div>

<button id="toggle" style="position:absolute; top: 120px;">Toggle</button>

Answer 3

这是使用 css 转换的另一种解决方案（出于移动设备上的性能目的，请参阅 @mate64 的答案），而无需使用动画和关键帧。

我创建了两个版本，可以从两侧滑入。

$('#toggle').click(function() {
  $('.slide-in').toggleClass('show');
});

.slide-in {
  z-index: 10; /* to position it in front of the other content */
  position: absolute;
  overflow: hidden; /* to prevent scrollbar appearing */
}

.slide-in.from-left {
  left: 0;
}

.slide-in.from-right {
  right: 0;
}

.slide-in-content {
  padding: 5px 20px;
  background: #eee;
  transition: transform .5s ease; /* our nice transition */
}

.slide-in.from-left .slide-in-content {
  transform: translateX(-100%);
  -webkit-transform: translateX(-100%);
}

.slide-in.from-right .slide-in-content {
  transform: translateX(100%);
  -webkit-transform: translateX(100%);
}

.slide-in.show .slide-in-content {
  transform: translateX(0);
  -webkit-transform: translateX(0);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="slide-in from-left">
  <div class="slide-in-content">
    <ul>
      <li>Lorem</li>
      <li>Ipsum</li>
      <li>Dolor</li>
    </ul>
  </div>
</div>

<div class="slide-in from-right">
  <div class="slide-in-content">
    <ul>
      <li>One</li>
      <li>Two</li>
      <li>Three</li>
    </ul>
  </div>
</div>

<button id="toggle" style="position:absolute; top: 120px;">Toggle</button>

Answer 4

我喜欢@mate64的答案，所以我将重用它并稍作修改，以创建下面的向下和向上滑动动画：

var $slider = document.getElementById('slider');
var $toggle = document.getElementById('toggle');

$toggle.addEventListener('click', function() {
    var isOpen = $slider.classList.contains('slide-in');

    $slider.setAttribute('class', isOpen ? 'slide-out' : 'slide-in');
});

#slider {
    position: absolute;
    width: 100px;
    height: 100px;
    background: blue;
    transform: translateY(-100%);
    -webkit-transform: translateY(-100%);
}

.slide-in {
    animation: slide-in 0.5s forwards;
    -webkit-animation: slide-in 0.5s forwards;
}

.slide-out {
    animation: slide-out 0.5s forwards;
    -webkit-animation: slide-out 0.5s forwards;
}
    
@keyframes slide-in {
    100% { transform: translateY(0%); }
}

@-webkit-keyframes slide-in {
    100% { -webkit-transform: translateY(0%); }
}
    
@keyframes slide-out {
    0% { transform: translateY(0%); }
    100% { transform: translateY(-100%); }
}

@-webkit-keyframes slide-out {
    0% { -webkit-transform: translateY(0%); }
    100% { -webkit-transform: translateY(-100%); }
}

<div id="slider" class="slide-in">
    <ul>
        <li>Lorem</li>
        <li>Ipsum</li>
        <li>Dolor</li>
    </ul>
</div>

<button id="toggle" style="position:absolute; top: 120px;">Toggle</button>

Answer 5

使用它从右向左滑动

$(document).ready(function() {
  $('a#click-a').click(function() {
    $('.nav').toggleClass('nav-view');
  });
});

/*nav*/

.nav {
  position: fixed;
  right: 0;
  top: 70px;
  width: 250px;
  height: calc(100vh - 70px);
  background-color: #333;
  transform: translateX(100%);
  transition: transform 0.3s ease-in-out;
}

.nav-view {
  transform: translateX(0);
}

.nav ul {
  margin: 0;
  padding: 0;
}

.nav ul li {
  margin: 0;
  padding: 0;
  list-style-type: none;
}

.nav ul li a {
  color: #fff;
  display: block;
  padding: 10px;
  border-bottom: solid 1px rgba(255, 255, 255, 0.4);
  text-decoration: none;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
<div class="menu">
  <a href="#" id="click-a">Toggle</a>
</div>


<div class="nav ">
  <ul>
    <li><a href="#">HOME</a></li>
    <li><a href="#">ABOUT</a></li>
    <li><a href="#">SERVICES</a></li>
    <li><a href="#">CONTACT</a></li>
  </ul>
</div>
