html - 如何摆脱 'settle blur' CSS 效果

Question

我目前有一个我悬停在其上的图 block 最初是模糊的。图像缩小后，这种模糊会稳定下来并在图 block 上产生不良效果。请查看我粘贴的代码。它应该让您对我在说什么有一个清晰的认识。

我尝试在图像悬停前后修改 CSS，但这并没有改变任何东西。

您是否注意到将鼠标悬停在图像上并进行缩放后，图像有轻微的不模糊/稳定？我希望摆脱它并使其模糊。

Answer 1

要在 Firefox 上获得模糊效果，只需添加 filter: blur(5px); 以及 -webkit-filter:，模糊效果也适用于 FF35+。


至于那里出现的不模糊，实际上是一个发生在 Chrome 上的错误(可能还有所有其他 webkit 浏览器)。但这不会发生在 Firefox 上。

所以要修复它，您需要添加:transform: translateZ(0);，这不会导致任何视觉差异，并且会解决 Chrome 上的问题。
