使用 CSS3 制作一组超时尚的动画按钮效果

　　通过 CSS3 的新特性，我们创作出好的交互和效果的可能性大大增加。这篇文章中，我想与大家分享一些 CSS3 动画按钮效果。我们的想法是创建一个具有不同风格的一些动画链接元素，鼠标悬停时有动画效果和活动状态。

HTML 示例代码：

<a href="#" class="a-btn">
    <span class="a-btn-slide-text">$29</span>
    <img src="images/icons/1.png" alt="Photos" />
    <span class="a-btn-text"><small>Available on the Apple</small> App Store</span> 
    <span class="a-btn-icon-right"><span></span></span>
</a>

CSS 示例代码：

.a-btn{
    background: linear-gradient(top, #a9db80 0%,#96c56f 100%);
    padding-left: 90px;
    padding-right: 105px;
    height: 90px;
    display: inline-block;
    position: relative;
    border: 1px solid #80ab5d;
    box-shadow: 
        0px 1px 1px rgba(255,255,255,0.8) inset, 
        1px 1px 3px rgba(0,0,0,0.2);
    border-radius: 4px;
    float: left;
    clear: both;
    margin: 10px 0px;
    overflow: hidden;
    transition: box-shadow 0.3s ease-in-out;
}
.a-btn img{
    position: absolute;
    left: 15px;
    top: 13px;
    border: none;
    transition: all 0.3s ease-in-out;
}
.a-btn .a-btn-slide-text{
    position: absolute;
    font-size: 36px;
    top: 18px;
    left: 18px;
    color: #6d954e;
    opacity: 0;
    text-shadow: 0px 1px 1px rgba(255,255,255,0.4);
    transition: opacity 0.2s ease-in-out;
}
.a-btn-text{
    padding-top: 13px;
    display: block;
    font-size: 30px;
    text-shadow: 0px -1px 1px #80ab5d;
}
.a-btn-text small{
    display: block;
    font-size: 11px;
    letter-spacing: 1px;
}
.a-btn-icon-right{
    position: absolute;
    right: 0px;
    top: 0px;
    height: 100%;
    width: 80px;
    border-left: 1px solid #80ab5d;
    box-shadow: 1px 0px 1px rgba(255,255,255,0.4) inset;

.a-btn-icon-right span{
    width: 38px;
    height: 38px;
    opacity: 0.7;
    border-radius: 20px;
    position: absolute;
    left: 50%;
    top: 50%;
    margin: -20px 0px 0px -20px;
    border: 1px solid rgba(0,0,0,0.5);
    background: #4e5c50 url(../images/arrow_down.png) no-repeat center center;
    box-shadow: 
        0px 1px 1px rgba(255,255,255,0.3) inset, 
        0px 1px 2px rgba(255,255,255,0.5);
