页面完全加载后会加载一些图像

标签: html

我有一个问题,当我向下滚动网站上的其他图像时,它们是白色的,但是图像在一秒钟后显示。

我一直在四处寻找解决问题的方法,但是没有运气。

我的网站是:https://lukasstauersboel.dk/

由于我有预加载器,第一个图像加载正常,但其他图像却没有。

我拥有的代码:

您的视差镜像div具有css属性visibility: hidden,直到最后一个相关数据视差div出现在屏幕上。然后它收到一个visibility: visible并解释了闪烁。

它在图书馆示例网站上效果很好,因为它们的图像宽1400像素,而您的图像宽4800像素(取决于图像)。您应该考虑将图像调整为适合网络的尺寸和权重。 IMO 1200px是在任何视口和设备上的图像质量和加载速度之间的良好折衷。
