CSS渐变 - 少Mixins

Question

我只是想知道是否有可能通过应用像CSS或Lightning到CSS代码的东西来改变较少mixin梯度的颜色？

这里是少的Mixin：

.css-gradient(@from: #20416A, @to: #3D69A5) { 
    background-color: @to; 
    background-image: -webkit-gradient(linear, left top, left bottom, from(@from), to(@to)); 
    background-image: -webkit-linear-gradient(top, @from, @to); 
    background-image: -moz-linear-gradient(top, @from, @to); 
    background-image: -o-linear-gradient(top, @from, @to); 
    background-image: -ms-linear-gradient(top, @from, @to); 
    background-image: linear-gradient(top, @from, @to); 
} 

在更短的文件，我想这样做：

#div { 
    width:100px; 
    height:100px; 
    .css-gradient (darken, 10%); 
} 

不知道这是可能的，或是否有另一种我应该这样做。

Answer 1

我会做到这一点，像这样：

.css-gradient(darken(#20416A,10%),darken(#3D69A5,10%)) 

当然，你也可以这样做：

.css-gradient(@from: #20416A, @to: #3D69A5) { 
    background-color: @to; 
    background-image: -webkit-gradient(linear, left top, left bottom, from(@from), to(@to)); 
    background-image: -webkit-linear-gradient(top, @from, @to); 
    background-image: -moz-linear-gradient(top, @from, @to); 
    background-image: -o-linear-gradient(top, @from, @to); 
    background-image: -ms-linear-gradient(top, @from, @to); 
    background-image: linear-gradient(top, @from, @to); 
} 
.css-gradient(darken,@amount: 10%, @from: #20416A, @to: #3D69A5){ 
    .css-gradient(darken(@from,@amount),darken(@to,@amount)); 
} 

然后叫它：

.css-gradient(darken,10%); 

或：

.css-gradient(#20416A, #3D69A5); 

或：

.css-gradient(darken,5%,#00ff00,#ff0000);
