我们在网站上有一个很大的应用程序,我们有一些链接,比如说蓝色的就像这个网站上的蓝色链接。现在我想做一些其他的链接,但是用浅一点的颜色。显然,我可以简单地通过在CSS文件中添加十六进制代码来做,但我们的网站让用户决定他们想要的自定义配置文件/网站(如Twitter)的颜色。
所以,我的问题是:我们能减少百分比的颜色吗?
让我们说下面的代码是CSS:
a {
color: blue;
}
a.lighter {
color: -50%; // obviously not correct way, but just an idea
}
OR
a.lighter {
color: blue -50%; // again not correct, but another example of setting color and then reducing it
}
有没有办法将颜色减少一个百分比?
把它们结合在一起,一个纯粹用DIV和CSS做的表解决方案,试试吧;)浏览器应该通过....支持RGBA颜色

我知道已经很晚了,但是,你可以使用一个包装器来改变你的按钮和rgba颜色函数的不透明度级别,正如在其他答案中所说,但没有明确的例子。
这是一支笔:
