更少的CSS如何在mixin中修改父属性 [英] LESS CSS how to modify parent property in mixin
问题描述
我正在寻找一种语法更少的东西来做类似的事情:
I'm looking for a less syntax to do something like that:
.button-default{
background-color: rgb(100,200,250);
:hover{
.button-hover-effect-mixin();
}
}
.button-warning{
background-color: rgb(250,100,0);
:hover{
.button-hover-effect-mixin();
}
}
.button-hover-effect-mixin(){
background-color: darken(PARENT.background-color, 50%);
}
我知道如何使用参数或全局变量来执行此操作,但是悬停效果选择不一定总是设计为更改背景颜色.
I know how to do that with a parameter or a global variable but the hover-effect schould not always be designed to change the background-color.
推荐答案
如果您的意思是.button-default
和.button-warning
是.button-hover-effect-mixin
的那些父代",那么您的朋友就是
If you mean the .button-default
and .button-warning
are those "PARENT"s for the .button-hover-effect-mixin
then your friends are variables:
.button-default {
@background-color: rgb(100, 200, 250);
background-color: @background-color;
&:hover {
.button-hover-effect-mixin();
}
}
.button-warning {
@background-color: rgb(250, 100, 0);
background-color: @background-color;
&:hover {
.button-hover-effect-mixin();
}
}
.button-hover-effect-mixin() {
background-color: darken(@background-color, 50%);
}
您还可以将此变量设置为.button-hover-effect-mixin
的参数.另外,不要错过:hover
选择器附近的&
(没有&
它将扩展到.button-default :hover
,这可能不是您所需要的,请参见
You also can make this variable to be a parameter of .button-hover-effect-mixin
. Additionally don't miss &
near :hover
selector (without &
it expands to .button-default :hover
and this probably is not what you need, see Nesting).
而且...如果方向正确,并且这些颜色是按钮之间的唯一区别,那么我会将整个代码段重写为类似这样的内容:
And... if this goes in right direction and those colors are the only difference between the buttons I would rewrite the whole snippet to something like this:
.button(default, rgb(100, 200, 250));
.button(warning, rgb(250, 100, 0));
.button(@name, @color) {
.button-@{name} {
background-color: @color;
&:hover {
background-color: darken(@color, 50%);
}
}
}
