<div class="container">
     <img src="http://i.stack.imgur.com/2OrtT.jpg"/>
</div>

<style>
.container {
       width: 150px;
       height: 100px;
       overflow: hidden;
}
</style>

There are three differences:

Providing width:100% on the style. This is helpful if you are using bootstrap and want the image to stretch all the available width. Specifying the height property is optional, You can remove/keep it as you need .cover { object-fit: cover; width: 100%; /*height: 300px; optional, you can remove it, but in my case it was good */ } By the way, there is NO need to provide the height and width attributes on the image element because they will be overridden by the style. so it is enough to write something like this. <img class="cover" src="url to img ..." />

使用溢出容器:隐藏

为了适应图像在全屏试试这个:

平铺方式:圆形;

你必须在CSS中使用background-size: cover

JS代码

 <div>
   <div className={styles.banner}>banner</div>
 </div>

css代码

.banner{
  background: 
    url("./images/home-bg.jpg");
  background-size: cover;
  height: 53rem;
  width: 100%;
}

对象匹配不工作 Background-size: contains也不工作

你可以通过“伸缩”显示来实现。对我来说!：

.avatar-img { display: flex; justify-content: center; align-items: stretch; border-radius: 50%; border: 1px solid #dee2e6; height: 5.5rem; width: 5.5rem; overflow: hidden; } .avatar-img > img { flex-grow: 1; object-fit: cover; } <div> <div class="avatar-img"> <img src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSqczw3Fb_TYsj0hbPEy0u7Ay2bVq1KurD6hw&amp;usqp=CAU" alt="Test!'s profile photo"> </div> <div class="avatar-img"> <img src="https://i.pinimg.com/236x/a1/37/09/a137098873af3bf6180dd24cbe388ae9--flower-iphone-wallpaper-wallpapers-flowers.jpg" alt="Test!'s profile photo"> </div> </div>
