I want to show an image from an URL with a certain width and height even if it has a different size ratio. So I want to resize (maintaining the ratio) and then cut the image to the size I want. I can resize with html img property and I can cut with background-image. How can I do both? Example: This image: Has the size 800x600 pixels and I want to show like an image of 200x100 pixels With img I can resize the image 200x150px: <img style="width: 200px; height: 150px;" src="http://i.stack.imgur.com/wPh0S.jpg"> That gives me this: <img style="width: 200px; height: 150px;" src="https://i.stack.imgur.com/wPh0S.jpg"> And with background-image I can cut the image 200x100 pixels. <div style="background-image: url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;"> </div> Gives me: <div style="background-image:url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;"> </div> How can I do both? Resize the image and then cut it the size I want?

你试过用这个吗?
.centered-and-cropped { object-fit: cover }
我需要调整图像的大小，中心(垂直和水平)，然后裁剪它。
我很高兴地发现，它可以在一个css行中完成。 在这里查看示例:http://codepen.io/chrisnager/pen/azWWgr/?editors=110
下面是这个例子的CSS和HTMLcode:
.居中剪裁{对象合身:封面} <标题>原始h1 > < / <img height="200" src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/3174/bear.jpg" alt="熊"> <标题> object-fit:封面h1 > < / <img class="center -and-裁剪" width="200" height="200" style="border-radius:50%" src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/3174/bear.jpg" alt="熊">

img {
position: absolute;
clip: rect(0px, 140px, 140px, 0px);
}
<img src="w3css.gif" width="100" height="140" />
生活例子: https://jsfiddle.net/de4Lt57z/
HTML:
<div class="crop">
<img src="example.jpg" alt="..." />
</div>
CSS:
.crop img{
width:400px;
height:300px;
position: absolute;
clip: rect(0px,200px, 150px, 0px);
}
解释: 在这里，图像是根据图像的宽度和高度值调整大小。裁剪是通过剪辑属性完成的。
有关剪辑属性的详细信息请参见: http://tympanus.net/codrops/2013/01/16/understanding-the-css-clip-property/
.imgContainer {
overflow: hidden;
width: 200px;
height: 100px;
}
.imgContainer img {
width: 200px;
height: 120px;
}
<div class="imgContainer">
<img src="imageSrc" />
</div>
包含的div本质上是通过隐藏溢出来裁剪图像。
尝试使用clip-path属性:
剪切路径属性允许您将元素剪切为基本形状或 SVG源代码。 注意:clip-path属性将替换已弃用的剪辑 财产。
img { 宽度:150 px; 剪辑路径:插入(30px 35px); ｝ < img src = " http://i.stack.imgur.com/wPh0S.jpg " >
这里有更多的例子。
img {
position: absolute;
clip: rect(0px,60px,200px,0px);
}
