如何摆脱“模糊不清”的局面？ CSS效果

时间：2016-09-02 20:02:34

标签： html css css3

我目前有一块瓷砖，我最初模糊了它。在缩小图像之后，这种模糊类型稳定下来并在图块上产生不希望的效果。请查看我粘贴的代码。它应该让你对我正在谈论的内容有一个很好的了解。

我试图在图像悬停之后和之前搞乱CSS，但这并没有改变任何东西。

您是否注意到图像悬停并放大后会略微不模糊/稳定下来？我希望摆脱它并保持模糊。

1 个答案:

答案 0 :(得分：2)

要在Firefox上模糊，只需添加filter: blur(5px);和-webkit-filter:，模糊也可用于FF35 +。


至于那里出现的unblurring，实际上是一个在Chrome（可能是其他所有webkit浏览器）上发生的错误。但这并不是在Firefox上发生的。

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，并会解决Chrome上的问题。
