2014 HTML5/CSS3热门动画特效TOP10攻略

为了更好地呈现网站内容并提供更好的用户体验，动画特效在现代Web开发中扮演着重要角色。下面是2014年HTML5/CSS3热门动画特效TOP10攻略：

1. 球形菜单

球形菜单特效通过使用CSS3的transition和transform属性来实现。该特效展示了一个球形的菜单。原始代码如下所示：

<div class="container">
  <ul class="menu">
    <li><a href="#"><i class="icon1"></i></a></li>
    <li><a href="#"><i class="icon2"></i></a></li>
    <li><a href="#"><i class="icon3"></i></a></li>
    <li><a href="#"><i class="icon4"></i></a></li>
    <li><a href="#"><i class="icon5"></i></a></li>
    <li><a href="#"><i class="icon6"></i></a></li>
  </ul>
</div>

CSS部分：

.container{
  position: absolute;
  top: calc(50% - 100px);
  left: calc(50% - 100px);
}

.menu {
  list-style: none;
  margin: 0;
  padding: 0;
  display: block;
  position: relative;
  opacity: 1;
  transform: scale(1) rotateX(0deg) rotateY(-35deg);
  transform-style: preserve-3d;
  perspective: 2000px;
}

.menu li {
  position: absolute;
  width: 60px;
  height: 60px;
  background-color: #ffb53e;
  box-shadow: 0px 0px 5px rgba(0,0,0,0.1), 1px 1px 2px rgba(0,0,0,0.1);
  border-radius: 50%;
  transform-style: preserve-3d;
  animation: menu 1s ease-in-out forwards;
  animation-delay: 0.1s;
}

.icon1 {
  background: url(../images/icon1.png) no-repeat center;
}

.icon2 {
  background: url(../images/icon2.png) no-repeat center;
}

.icon3 {
  background: url(../images/icon3.png) no-repeat center;
}

.icon4 {
  background: url(../images/icon4.png) no-repeat center;
}

.icon5 {
  background: url(../images/icon5.png) no-repeat center;
}

.icon6 {
  background: url(../images/icon6.png) no-repeat center;
}

@keyframes menu {
  0% {
    top: 0px;
  }
  100% {
    top: calc(50% - 100px);
  }
}

2. 蒙板动画

蒙板动画特效提供了一种新颖的方式来展示图片和文本，特别是当它们以一种非线性的方式进行排列时。下面是样例代码：

<div class="wrapper">
  <div class="overlay">
    <h1 class="title">Cool CSS3 Text Masking Effect</h1>
    <p class="subtitle">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
  </div>
  <img src="https://picsum.photos/seed/picsum/800/800" alt="Masked Image" class="masked-image" />
</div>

CSS部分：

.wrapper {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  position: relative;
  width: 100vw;
  height: 100vh;
}

.overlay {
  position: relative;
  width: 70%;
  height: auto;
  margin-bottom: 24px;
  padding: 24px;
  background-color: rgba(25, 92, 255, 0.8);
  color: #FFF;
  text-align: center;
  overflow: hidden;
}

.overlay:before {
  content: '';
  position: absolute;
  top: 0px;
  left: -100%;
  width: 100%;
  height: 100%;
  background-color: #FFF;
  transform-origin: bottom right;
  transform: skewX(45deg);
  animation: reveal-before 0.5s forwards;
}

.overlay:after {
  content: '';
  position: absolute;
  top: 0px;
  right: -100%;
  width: 100%;
  height: 100%;
  background-color: #FFF;
  transform-origin: bottom left;
  transform: skewX(45deg);
  animation: reveal-after 0.5s forwards;
}

.masked-image {
  mask-image: url('https://www.w3schools.com/w3css/img_avatar2.png');
}
