我想要的效果仅在 Firefox 中工作,我假设 IE。我从一个透明图像开始,周围有一个蓝色背景的div 包装器。当用户将鼠标悬停在图像上时,我希望它放大并将不透明度恢复到 100%,而不会破坏div 包装器的设置宽度和高度。这在 Firefox 中完美运行,但是当我在 Chrome 中运行动画时,图像超过了它后面的蓝色div 包装器的宽度。这是我的代码,任何帮助将不胜感激&JS Fiddle http://jsfiddle.net/yaLupdzo/1/:

已知问题,如下所述:https://code.google.com/p/chromium/issues/detail?id=157218
在 Webkit 中,通过硬件加速,动画层在动画期间提升到不同的渲染图面,然后在动画完成后降级。
事实证明有一个简单的解决方案。通过向其添加轻量级动画,将容器元素"提升"到与硬件加速子元素相同的呈现层:
.tricky {
width: 200px;
height: 200px;
border-radius: 50%;
border: none;
background: #2373bd;
display: block;
overflow: hidden;
-webkit-transform:scale(1.0);
}
.tricky_image {
width: 200px;
height: 200px;
-webkit-transition: all .6s ease;
opacity: 0.7;
}
.tricky:hover {
-webkit-transform:scale(1.0);
}
.tricky:hover .tricky_image {
opacity: 1;
-webkit-transform:scale(1.2);
}
请参阅:http://jsfiddle.net/yaLupdzo/3/
请注意,我还向父容器的默认状态添加了一个简单的动画,以便在悬停时不会发生相同的问题。
-webkit-transform: scale(1.2);
-moz-transform: scale(1.2);
-o-transform: scale(1.2);
transform: scale(1.2);
您可以像这样重复代码以实现浏览器兼容性。
