给定一个透明的PNG显示一个简单的形状在白色,它是有可能以某种方式改变这通过CSS的颜色?某种叠加还是什么?

为了字面上改变颜色,你可以使用-webkit-filter来合并CSS转换,当有事情发生时,你可以调用你选择的-webkit-filter。例如:

img {
    -webkit-filter:grayscale(0%);
    transition: -webkit-filter .3s linear;
    }
img:hover 
    {
    -webkit-filter:grayscale(75%);
    }

Surfin' Safari - Blog Archive » CSS Masks WebKit now supports alpha masks in CSS. Masks allow you to overlay the content of a box with a pattern that can be used to knock out portions of that box in the final display. In other words, you can clip to complex shapes based off the alpha of an image. [...] We have introduced new properties to provide Web designers with a lot of control over these masks and how they are applied. The new properties are analogous to the background and border-image properties that already exist. -webkit-mask (background) -webkit-mask-attachment (background-attachment) -webkit-mask-clip (background-clip) -webkit-mask-origin (background-origin) -webkit-mask-image (background-image) -webkit-mask-repeat (background-repeat) -webkit-mask-composite (background-composite) -webkit-mask-box-image (border-image)

/* change image color to white */
filter: invert(100%) sepia(16%) saturate(7463%) hue-rotate(222deg) brightness(119%) contrast(115%);

/* change image color to red */`
filter: invert(16%) sepia(99%) saturate(7404%) hue-rotate(4deg) brightness(95%) contrast(118%);

/* change image color to green */
filter: invert(26%) sepia(89%) saturate(1583%) hue-rotate(95deg) brightness(96%) contrast(106%);

/* change image color to blue */
filter: invert(10%) sepia(90%) saturate(5268%) hue-rotate(245deg) brightness(109%) contrast(155%);

你可以使用滤镜:色调旋转(Ndeg),但如果图像是黑白的,色调将永远不会改变。

但是,你可以把它和滤镜结合起来:sepia(100)。这将为图像添加色彩,色彩旋转滤镜可以改变。

Sepia增加了一个相当不饱和的颜色,所以增强一点滤镜:饱和(50);这使得它的颜色更深,色彩旋转可以更好地工作。

然后把它们组合在一起:

滤镜:棕褐色(100)饱和(50)色调旋转(280度)

然后尝试旋转的程度,直到你找到你喜欢的颜色。

对我来说有效的解决方案是使用滤镜:投影

滤镜:水滴阴影的工作方式不同于常规的盒子阴影。

滤镜将阴影应用于真实形状(因此它支持透明图像)。

现在的技巧是“隐藏”真实的图像,只显示阴影。

请注意,我的用例是将图标的颜色修改为一种纯色,所以这种方法适合我,但可能不适用于其他用例
