使用 css transform:scale 时如何删除闪烁的线条？

Question

当我将鼠标悬停在图像上时，我一直在尝试消除这种难看的闪烁。我尝试将 -webkit-backface-visibility: hidden; 与 :hover 本身一起添加到悬停元素，但似乎无法动摇它。似乎问题只在 Chrome 和 Safari 上。 网址：http://best-law-firm-sites.com/lawpromo12/

Answer 1

您可以通过将transform scale 属性增加到 1.001 来解决此问题：

.hovereffect img{transform: scale(1.001);}

Answer 2

过去，当我使用背面可见性黑客来欺骗浏览器使用 3d 管道时，我也遇到过类似的奇怪行为。还有其他方法可以“欺骗”浏览器使用 3d 管道，例如：

.class{
    transform: translate3d(0,0,1);
}
