Question

我正在使用CSS背景渐变来创建透明的径向渐变效果。如果您在Chrome中查看：http://dev.aaronpitts.ch/unitymedia/index.html，您会看到它的工作方式（社交媒体，SEM，网页设计和开始您的旅程背景）。问题是其他浏览器不能保持平滑并切断边缘。有什么想法吗？

这是我正在使用的代码：

为避免梯度被切断，您需要在它到达容器的最近侧之前将其停止。

幸运的是，渐变语法closest-side中有一个关键字属性。

JSfiddle演示（各种选项）

使用明显渐变

的closest-side的

CSS

.closest-side {
    background: radial-gradient(
     ellipse closest-side, 
     rgba(0,0,0,1) 0%,
     rgba(255,255,255,1)75%,
     rgba(0,0,0,1) 100%);
}

如何在Chrome以外的浏览器中保持透明的径向背景平滑？
