CSS显示图像调整大小和裁剪

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?

如果你正在使用Bootstrap，尝试使用{background-size: cover; }对于<div>可能给div一个类说<div class="example" style=url('../your_image.jpeg');>所以它变成 div.example { background-size:封面}

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。

.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。

谢谢sanchothefat。

我对你的回答有改进的地方。由于裁剪是非常适合每一个图像，这个定义应该在HTML而不是CSS。

<div style="overflow:hidden;">
   <img src="img.jpg" alt="" style="margin:-30% 0px -10% 0px;" />
</div>

img {
  position: absolute;
  clip: rect(0px, 140px, 140px, 0px);
}

<img src="w3css.gif" width="100" height="140" />
