html 图像在移动的上未正确调整大小(在桌面上未正确调整大小)

我有一个宽度为90%设备宽度的幻灯片,图像也应该是相同的宽度(100%的父母),它在桌面上完美工作,但在移动的上不行。

即使在桌面上调整浏览器窗口的大小,幻灯片也会随着窗口缩放(高度和宽度都正确缩放),但在移动的浏览器上(即使选择“桌面模式”选项),幻灯片中包含的图像太大(幻灯片中的div大小正确,但图像本身太宽(大约是设备宽度的5倍)。我不知道为什么会发生这种情况,因为在桌面上,即使将浏览器窗口大小调整为较小的宽度,它也能完美地工作。
幻灯片内的图像(具有class .slideImg)的宽度被设置为其父级的100%,其父级是具有class .slidewrapper的div,其宽度是其父级的90%,其父级是具有class .slideDiv的div(其宽度被设置为'device-width')。
我做错了什么?为什么幻灯片中的图像在移动的上不能正确调整大小?
PS:此外,图像的宽度是正确的(至少在桌面上),但图像在高度上被拉伸(与原始图像相比宽高比发生了变化),我不明白为什么,因为我只为这些图像设置了宽度,而没有为它们或它们的父div设置任何高度值。如果有人知道,请让我知道为什么,我做错了什么。
幻灯片的HTML:

/* slideshow styles */
.slideDiv{
  width: device-width; /* set width of slideshow to device's width */
}

.slideContainer{
  width:90%; /* 90% of parent(slideDiv) width = 90% of 'device-width' */
  position:relative;
  overflow: hidden;
  z-index: 999;
  margin:auto;
  margin-top:1vh;
}
.slideWrapper{
  width:1200%; /* 12*100% because the slideshow contains 12 images, each of 100% width of the .slideContainer class */
  display: flex;
  animation: slide 100s infinite;
}

.slideImg{
  width: 100%; /*100% of parent which is 100% of slidecontainer = 90% of 'device width'*/

}

CSS中的device-width已弃用。(Reference)。
(Even虽然在viewport meta标签中它可能工作。
您可以使用100vw。此外,您可以使用aspect-ratio CSS property来设置所需的纵横比(可能与源代码相同)。
还可以看到这个。

/* slideshow styles */
.slideDiv{
  width: 100vw; /* set width of slideshow to 100% visual width */
}

.slideContainer{
  width:90%; /* 90% of parent(slideDiv) width = 90% of visual width */
  position:relative;
  overflow: hidden;
  z-index: 999;
  margin:auto;
  margin-top:1vh;
}
.slideWrapper{
  width:1200%; /* 12*100% because the slideshow contains 12 images, each of 100% width of the .slideContainer class */
  display: flex;
  animation: slide 100s infinite;
}

.slideImg{
  width: 100%; /*100% of parent which is 100% of slidecontainer = 90% of visual width*/
  aspect-ratio: 2/1; /*please set desired aspect ratio*/
}

您实际上有width: device-widht;,但即使device-width也是无效的属性值,因此被忽略。
.slideWrapper {display: flex}导致本质上较短的图像拉伸到较高图像的高度。
.slideImg是父.slideWrapperwidth: 100%,父.slideWrapper.slideContainer的100%1200%
