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;">&nbsp;</div> Gives me: <div style="background-image:url('https://i.stack.imgur.com/wPh0S.jpg'); width:200px; height:100px; background-position:center;">&nbsp;</div> How can I do both? Resize the image and then cut it the size I want?

img {
  position: absolute;
  clip: rect(0px, 140px, 140px, 0px);
}
<img src="w3css.gif" width="100" height="140" />

如果您正在使用<img>标记,那么Object-fit可能会帮助您

下面的代码将为您裁剪图像。你可以尝试一下合身的衣服

img {
  object-fit: cover;
  width: 300px;
  height: 337px;
}
<div class="crop">
    <img src="image.jpg"/>
</div>
.crop {
  width: 200px;
  height: 150px;
  overflow: hidden;
}
.crop img {
  width: 100%;
  /*Here you can use margins for accurate positioning of cropped image*/
}

你可以使用Kodem的图片调整服务。您可以通过http调用调整任何图像的大小。可以在浏览器中随意使用,也可以在生产应用程序中使用。

上传图片到你喜欢的地方(S3, imgur等) 将其插入到您的专用API url(从我们的仪表板)

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>

有像Filestack这样的服务可以帮你做这件事。

它们获取你的图像url,并允许你使用url参数来调整它的大小。这很简单。

将图像大小调整为200x100,但保持纵横比后,图像将如下所示

整个url看起来像这样

但重要的是

resize=width:200/crop=d:[0,25,200,100]
