javascript - 以响应方式使图像适合划分

Question

我正在尝试将整个图像放入分区中，并希望使用媒体查询使其响应。主要目的是在不拉伸图像的情况下将图像放入容器内，并且图像应该适合 div 标签。因此，即使我们拉伸屏幕，图像也应该在容器内响应，即使我缩小屏幕，它也应该在容器内响应。

我一直在尝试多种方式。我的最终代码是

.grid-container{
 width: 70%;
 margin: 90px auto;
}

.box {
    height: 200px;
    width: 100%;
    min-height: 200px;
    position: relative;
}
.box1{
    background: transparent url('https://i.picsum.photos/id/210/200/200.jpg?hmac=ofnpd0LAPvyH0juHuFCaLU6Y6jqJe4qpuc90jXbzUjY') no-repeat;
    height: 100%;
    position:relative;
    background-size: cover;
    background-position: center;
}
.box2{
   background: transparent url('https://i.picsum.photos/id/210/200/200.jpg?hmac=ofnpd0LAPvyH0juHuFCaLU6Y6jqJe4qpuc90jXbzUjY') no-repeat;
    opacity: 1;
    background-position:contain; 
    background-repeat:no-repeat; 
   }
.box3{
   background: transparent url('https://i.picsum.photos/id/210/200/200.jpg?hmac=ofnpd0LAPvyH0juHuFCaLU6Y6jqJe4qpuc90jXbzUjY') no-repeat;
    opacity: 1;
    background-position:contain; 
    background-repeat:no-repeat; 
   }
.box4{
   background: transparent url('https://i.picsum.photos/id/210/200/200.jpg?hmac=ofnpd0LAPvyH0juHuFCaLU6Y6jqJe4qpuc90jXbzUjY') no-repeat;
    opacity: 1;
    background-position:contain; 
    background-repeat:no-repeat; 
}
.box5{
background: transparent url('https://i.picsum.photos/id/210/200/200.jpg?hmac=ofnpd0LAPvyH0juHuFCaLU6Y6jqJe4qpuc90jXbzUjY') no-repeat;
    opacity: 1;
    background-position:contain; 
    background-repeat:no-repeat; 
}

.sub-con {
 display: grid;
 grid-template-columns: 1fr 1fr 1fr;
 grid-column-gap: 10px;
 grid-row-gap: 10px;
}
 
@media only screen and (max-width: 1000px) {
 .sub-con {
 grid-template-columns: 1fr 1fr;
 }
}
 
@media only screen and (max-width: 700px) {
 .sub-con {
 grid-template-columns: 1fr;
 }
}

            <div class="grid-container">
            <div class="sub-con">
            <div class="box1 box"></div>
            <div class="box2 box"></div>
            <div class="box3 box"></div>
            <div class="box4 box"></div>
            <div class="box5 box"></div>
            </div>
            </div>
