首页banner的酷炫效果多来自全屏大图的幻灯片动画，下面提供一种完美兼容的jquery动画特效：全新jquery多点滑动幻灯片——全屏动画animateSlide（代码完全原创）。


直接上代码，把html、css和jquery代码copy到页面上即可呈现完美画面。


html代码如下：




<div class="animateSlide">

  <div class="animateSlideImgWrap">

    <div class="animateSlideImgBox present">

      <p class="text1">亲，这是第一行标题</p>

      <p class="text2">AAAAAAAAAAAAAAAAAAAAA</p>

      <!--<img class="img" alt="" src="img/1.png" />-->

      <div class="img" style="width: 500px; height: 390px; background: #ffaeae; opacity: 0.6;"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->

    </div>

    <div class="animateSlideImgBox">

      <p class="text1">亲，这是一行宣传语</p>

      <p class="text2">BBBBBBBBBBBBBBBBBBBBB</p>

      <!--<img class="img" alt="" src="img/2.png" />-->

      <div class="img" style="width: 500px; height: 390px; background: #aeffb2; opacity: 0.6;"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->

    </div>

    <div class="animateSlideImgBox">

      <p class="text1">亲，这是一个奇迹啊</p>

      <p class="text2">CCCCCCCCCCCCCCCCCCCCC</p>

      <!--<img class="img" alt="" src="img/3.png" />-->

      <div class="img" style="width: 500px; height: 390px; background: #aebdff; opacity: 0.6;"></div><!-- 实际项目中用上面注释的半透明png图片，目前临时用div代替图片 -->
