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?
当前回答
img {
position: absolute;
clip: rect(0px,60px,200px,0px);
}

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}
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>
在裁剪类中，放置你想要显示的图像大小:
.crop {
width: 282px;
height: 282px;
overflow: hidden;
}
.crop span.img {
background-position: center;
background-size: cover;
height: 282px;
display: block;
}
html看起来像这样:
<div class="crop">
<span class="img" style="background-image:url('http://url.to.image/image.jpg');"></span>
</div>
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/
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 " >
