我有一个弹出模式,它有一个固定位置,宽度和高度为 100%。
modal 中的内容有 max-width: 90%;
和 max-height: 90%
图像也有这些值,但问题是它在改变高度时不保持纵横比,但在改变宽度时保持纵横比。 (视频说明一切)

编辑:
当我给 .metalPopup
类 display: block
时,图像保持纵横比。但它使宽度保持为原始 img
宽度,即使图像是整个块的一小部分。

所以我只是将 .metalPopup
max-height 改为 height: 100%;
并且它现在似乎可以工作并且不会拉伸图像,因为 .metalImg
现在具有删除的 max-height .metalName
的高度(现在是 position: relative
,因为如果我愿意,它不会响应式地将模态居中,但仍然可以添加到相对定位中,只需减去它的高度)。< /p>

答案 1 :(得分:1)
如果您设置高度,通常最好将宽度设为自动,反之亦然。
.yourclass {
max-height: 90%;
max-width: (either unset or auto)
}
答案 2 :(得分:1)
您可以在 CSS 中使用 aspect-ratio 来保持视频的特定比例。
video {
width: 90%;
aspect-ratio: 16/9 ; // due to this video will maintain aspect ratio of 16/9
}
这几乎被所有现代浏览器支持,并且会让你编写更少的代码。

这个怎么样。对你有用吗?
img {
width: auto;
height: auto;
max-width:90%;
max-height:90%;
}
