如何防止图像在家长的边界外缩放？

Question

我提供了不同服务的列表，每个服务都有一个图像，标题和说明。我已经设置了它，以便在鼠标悬停时将图像缩放为1.3倍大小。缩放工作，但这样做时忽略父母的边界。

我已经捕获了它在行动中看起来像的GIF。

这是我的工作的代码。

.cleaningservices { 
 
    max-width: 250px; 
 
    max-height: 250px; 
 

 
} 
 

 
    /* Default state of the image */ 
 
    .hover01 img { 
 
     -webkit-transform: scale(1); 
 
     transform: scale(1); 
 
     -webkit-transition: .3s ease-in-out; 
 
     transition: .3s ease-in-out; 
 
    } 
 

 
    /* Scale the image to 1.3 it's size on mouse hover */ 
 
    .hover01:hover img { 
 
     -webkit-transform: scale(1.3); 
 
     transform: scale(1.3); 
 
    }

您可以将图像添加到一个div并给DIV overflow:hidden;

.hover01 img { 
 
    -webkit-transform: scale(1); 
 
    transform: scale(1); 
 
    -webkit-transition: .3s ease-in-out; 
 
    transition: .3s ease-in-out; 
 
    width:100%; 
 
} 
 
.hover01:hover img { 
 
    -webkit-transform: scale(1.3); 
 
    transform: scale(1.3); 
 
} 
 

 
.img-parent{ 
 
    overflow:hidden; 
 
}

创建一个img容器，您在其中设置overflow: hidden;。我在body上添加了一个背景颜色，以便您看到它的工作原理。

body { 
 
    background-color: #f0f0f0 !important; 
 
    padding: 50px; 
 
} 
 
.noverflow { 
 
    overflow: hidden; 
 
} 
 
.thumbnail { 
 
    background-color: #fff; 
 
} 
 
.hover01 img { 
 
    -webkit-transform: scale(1); 
 
    transform: scale(1); 
 
    -webkit-transition: .3s ease-in-out; 
 
    transition: .3s ease-in-out; 
 
} 
 
.hover01:hover img { 
 
    -webkit-transform: scale(1.1); 
 
    transform: scale(1.1); 
 
}

只使用overflow: hidden;

.hover01 img { 
    -webkit-transform: scale(1); 
    transform: scale(1); 
    -webkit-transition: .3s ease-in-out; 
    transition: .3s ease-in-out; 
    overflow: hidden; 
}
