更新：事实证明，这是由于Chrome 中的一个错误造成的。我仍在寻找解决方法。我试图通过设置元素来在 Chrome 中使用延迟loading="lazy"加载img。我还使用以下方法让图像适合：img {
max-width: 100%;
height: auto;
}不幸的是，在 Chrome 中，在图像实际加载之前显示的图像占位符具有方形长宽比。img它不遵循元素width/属性中设置的宽高比height。这种情况发生在以下条件下：仅在 Chrome 中（不在 Firefox 75 中，Firefox 75 也支持延迟加载）。仅当设置loading="lazy". 如果没有此属性，则保留纵横比。即使在延迟加载的情况下，是否有解决方案可以保留width/中设置的图像的纵横比？height这是一篇文章，建议我所做的事情应该有效。另请参阅文章中嵌入的视频，也是这样说的。如果使用 Chrome 的开发者工具限制网络速度，您可以通过下面的示例观察到问题。我提供了一个屏幕录制来说明问题。我不希望图像大小在加载后发生变化，因为它会导致页面元素移动。https://i.stack.imgur.com/poiEP.gif 一个最小的例子HTML：<html><head> <link rel="stylesheet" type="text/css" href="style.css"></head><body><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.

也许经典的 padding-top hack 可能会有所帮助作为一种解决方法。
body {
max-width: 600px;
padding: 20px;
}
img {
border: solid black;
max-width: 100%;
height: auto;
box-sizing: border-box;
}
@supports (--foo: 1) {
.aspect,
.aspect-inline {
position: relative;
}
.aspect {
padding-top: calc(var(--height) / var(--width) * 100%);
height: 0;
display: block;
}
.aspect-inline {
display: inline-block;
vertical-align: middle;
}
.aspect img,
.aspect-inline img {
position: absolute;
top: 0;
max-height: 100%;
}
}
