Question

我的网站在标题下方的一个部分中有照片幻灯片。当幻灯片显示到第三张照片时，它会停止。我想知道如何将第三张照片转换回第一张照片，然后在所有照片中使用相同的动画继续播放该循环？动画是从当前照片右侧滑入的下一张照片。我的代码如下。

Answer 1

添加一个名为.no_trans的css类，它将禁用转换。该类将具有以下规则

.no_trans{
  transition:none !important;
    -webkit-transition:none !important;
    -moz-transition:none !important;
    -ms-transition:none !important;
    -o-transition:none !important;
}

当计数器大于no时。您禁用的图像删除过渡类并反转图像的位置（这将是快速的）

计数器然后以no开头。少于没有。您将其重置为0后的元素

流程重新启动

＆＃13;

.no_trans {
  transition: none !important;
  -webkit-transition: none !important;
  -moz-transition: none !important;
  -ms-transition: none !important;
  -o-transition: none !important;
}
