在我的网站中，我希望能够允许用户将鼠标悬停在图像上并通过过渡放大图像。我已经能够成功实现过渡，但是，当图像被放大时，它不断地与其他元素重叠。我当前的布局是在网格中排序的，并且容器已被赋予属性溢出：隐藏。我试图在每个元素悬停时为其分配 z-index 值 -1，但是层之间存在连续变化，这看起来很可怕。如何允许放大每个图像而不与任何其他元素重叠？这是我的 jsfiddle：https ://jsfiddle.net/Syed213shah/4u0vh5Lb/body { background-color: #800020;}body, html { height: 100%; margin: 0;} #box-container { display: flex; height: 600px; width: 75%; }.container { min-height: 500px; width: 100%; display: grid; grid-template-columns: 50% 2fr; grid-template-rows: 50% 2fr; overflow: hidden; position: static;}.item1 { background-image: url('https://pbs.twimg.com/media/D5gQCxCW0AE0skl.jpg'); width: 100%; height: 200%; transition: all 0.5s ease-in-out; position: relative;}.item1:hover { transform: scale(1.1); z-index: -1;}.item2 { background-image: url('https://media-public.fcbarcelona.com/20157/0/document_thumbnail/20197/172/175/246/32944044/1.0-10/32944044.jpg?t=1475841685000'); grid-column: 2; grid-row: 2; width: 100%; height: 400px; transition: all 0.5s ease-in-out; position: relative;}.item2:hover { transform: scale(1.1); z-index: -1;}.item3 { background-image: url('https://e00-marca.uecdn.es/assets/multimedia/imagenes/2019/10/26/15721062687641.jpg'); grid-column: 2; grid-row: 1; width: 100%; height: 400px; transition: all 0.5s ease-in-out; position: relative;}.item3:hover { transform: scale(1.1); z-index: -1;}

我认为使用伪元素或内部标签（如您所愿）并缩放此元素设置其父元素（我们的<a>）更简单，overflow:hidden;以防止您的错误。
在我的例子中，我使用了一个伪元素。我将这些代码行添加到您的 CSS（我还注释了一些行）：
.container a {
overflow: hidden;
}
.container a::after {
height:100%;
width:100%;
content: "";
position: absolute;
transition: all 0.5s ease-in-out;
z-index:-1;
}
.item1::after{
background-image: url('https://pbs.twimg.com/media/D5gQCxCW0AE0skl.jpg');
}
body {
background-color: #800020;
}
body, html {
height: 100%;
margin: 0;
}
#box-container {

我没有碰你的 HTML。

而不是变换：在您的图像上缩放，也许使用背景大小和背景位置可能会给您寻求的结果，并对您已经使用的实际裁剪进行更多控制。
附带的 jsfiddle 使用这样的示例修改了您的代码。我确实为文本叠加保留了变换比例。还要注意图像容器需要一个 overflow:hidden 以防止单元格之间的悬停交互。
这是您相应修改的 css；
