我希望我的元素具有多种颜色的锐利背景渐变。 在Chrome上它工作正常,但在Firefox上它在转换时有模糊的边缘。

以下是以下示例:

火狐:

Firefox

铬:

Chrome

如何让它在Firefox上运行?

这是一种解决方法,而非修复方法。

在我的环境中,我实际上在js小提琴中观察到相反的结果。在运行FF 54.0.1的Mac Sierra上,我获得了清晰的过渡。但是,在Chrome 60.0.3112.101上,我得到了模糊转换。因此,结果可能会因环境而异。

由于这不应该是一个连续的渐变,因此我可以提出一个不同的解决方案,在任何浏览器中都能呈现清晰。基本上,创建一个容器来容纳纯色框,给它一个相对位置,并将元素放在容器内的绝对位置。

HTML

<div class="container">
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
<div class="box4"></div>
<div class="box5"></div>
<div class="box6"></div>
<div class="my-element">my element</div>
</div>

CSS

.container {width:100%;margin:50px 0px 50px 0px;position:relative;left:0px;right:0px;}
.container div {float:left;height:12px;width:16.6%;}
.box1 {background-color:#ffd503;}
.box2 {background-color:#f36f21;}
.box3 {background-color:#da2128;}
.box4 {background-color:#009066;}
.box5 {background-color:#b51e83;}
.box6 {background-color:#005a9e;}

.my-element {position:absolute;top:0px;left:0px;}
