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?


当前回答

在大多数浏览器中,你可以使用过滤器:

在<img>元素和其他元素的背景图像上 并在CSS中静态设置它们,或者使用JavaScript动态设置它们

请看下面的演示。


< img >元素

你可以把这个技巧应用到<img>元素上:

#original, #changed { 宽度:45%; 填充:2.5%; 浮:左; } #{改变 -webkit-filter:色调旋转(180度); 滤镜:色调旋转(180度); } <img id="original" src="http://i.stack.imgur.com/rfar2.jpg" /> <img id="changed" src="http://i.stack.imgur.com/rfar2.jpg" />

背景图片

你可以把这个技巧应用到背景图像上:

#original, #changed { 背景:url (http://i.stack.imgur.com/kaKzj.jpg); background-size:封面; 宽度:30%; 利润率:0 10% 0 10%; padding-bottom: 28%; 浮:左; } #{改变 -webkit-filter:色调旋转(180度); 滤镜:色调旋转(180度); } < div id = "原始" > < / div > < div id = "改变" > < / div >

JavaScript

你可以使用JavaScript在运行时设置一个过滤器:

var element = document.getElementById("changed"); Var过滤器= '色调-旋转(120度)饱和(2.4)'; 元素。Style ['-webkit-filter'] = filter; 元素。Style ['filter'] = filter; #original, #changed { 利润率:0 10%; 宽度:30%; 浮:左; 背景:url (http://i.stack.imgur.com/856IQ.png); background-size:封面; padding-bottom: 25%; } < div id = "原始" > < / div > < div id = "改变" > < / div >

回答是因为我在寻找解决办法。

如果你的背景是白色或黑色,@chrscblls回答中的钢笔效果很好,但我的不是。此外,这些图像是用ng-repeat生成的,所以我不能在我的css中有他们的url,而且你不能在img标签上使用::after。

所以,我想了一个变通的办法,如果人们在这里也跌倒了,我想它可能会帮助到他们。

所以我所做的几乎是一样的,只有三个主要区别:

url是在我的img标签,我把它(和一个标签)在另一个div::后将工作。 “混合-混合模式”设置为“差”,而不是“相乘”或“筛选”。 我用完全相同的值添加了一个::before,因此::after将执行::before所做的'difference'的'difference',并取消它-self。

要改变它从黑色到白色或白色到黑色的背景颜色需要是白色。 从黑色到彩色,你可以选择任何颜色。 从白色到彩色,你需要选择你想要的颜色相反的颜色。

.divClass{
   position: relative;
   width: 100%;
   height: 100%;
   text-align: left;
}
.divClass:hover::after, .divClass:hover::before{
   position: absolute;
   width: 100%;
   height: 100%;
   background: #FFF;
   mix-blend-mode: difference;
   content: "";
}

因为我张贴了这个答案,我用不同的方法制作了另一支笔:

* { box-sizing: border-box; } body { background-color: CadetBlue; font-family: "Lato", sans-serif; text-align: center; } button { display: flex; justify-content: center; min-width: 182px; padding: 0.5em 1em; margin: 2em auto; cursor: pointer; pointer-events: auto; border-radius: 4px; border: none; background: #85b5b7; box-shadow: 0 6px #6fa8aa; } label { font-weight: 400; font-size: 24px; margin: auto 0; color: white; } .icon { height: 64px; width: 64px; background-color: white; -webkit-mask-repeat: no-repeat; mask-repeat: no-repeat; -webkit-mask-position: left center; mask-position: left center; -webkit-mask-size: auto 48px; mask-size: auto 48px; mask-mode: luminance; -webkit-mask-image: url("https://upload.wikimedia.org/wikipedia/commons/thumb/d/d1/Bubbles-alt-icon.png/640px-Bubbles-alt-icon.png"); mask-image: url("https://upload.wikimedia.org/wikipedia/commons/thumb/d/d1/Bubbles-alt-icon.png/640px-Bubbles-alt-icon.png"); } button label span { color: #395f60; } button:hover { color: #395f60; transform: translatey(4px); box-shadow: 0 2px #6fa8aa; } button:hover .icon { background-color: #395f60; } <button> <div class="icon"></div> <label> white to <span>color</span></label> </button>

我在谷歌上找到了这个,我发现最适合我的工作…

HTML

<div class="img"></div>

CSS

.img {
  background-color: red;
  width: 60px;
  height: 60px;
   -webkit-mask-image: url('http://i.stack.imgur.com/gZvK4.png');
}

是的:)

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)
