html - 移动网页设计 HTML ul 在旋转设备时影响其下方的图像

Question

您好，我的网站有问题。它在计算机上运行良好，但在移动设备上，我使用的价格表影响了它下面的图像。价格表在 ul 类中，当我查看下面的纵向图片然后切换到横向时，图像消失了。如果我取出所有价格表，图像将在手机上旋转并且不会消失。所以我知道 ul 类会影响图像，但我不知道如何修复它。

    <ul class="pricing_table">

            <li class="price_block">
            <h3><h3>Mini Facial </h3></h3>

            <div class="price">
                <div class="price_figure">
                    <span class="price_number">&pound; 15</span>
                    <span class="price_tenure">30 minutes</span>

                </div>
            </div>

这不是 ul 的错，这是视差插件。当您向下滚动纵向 View 时，它会使用 javascript 将背景位置更改为某个值。然后，您将设备旋转到横向，即使从页面顶部到带有图片的容器的距离发生变化，插件设置的值仍然相同。
