      <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 -->

      <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 -->
