更少的父选择器 [英] parent selector in less
本文介绍了更少的父选择器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
通常较少引用父选择器的是:
Normally in less to reference a parent selector is:
.parent {
.grand-pa & {
/* this rules will apply to: .grand-pa .parent {....}
background: grey;
}
}
我想要做的是类似的事情. HTML的示例代码:
What I'm trying to do is something similar. example code HTML:
<div class="panel panel-parent">
<div class="panel-child">
{{content}}
</div>
</div>
更少的代码:
.panel {
.panel-child {
// some rules
&.panel-parent & { //<=== IS IT POSSIBILE SOMETHING LIKE THIS??
// .panel.panel-parent .panel-child{...}
}
}
}
我发现的唯一解决方案是重复.panel-child:
The only solution I have found is to repeat .panel-child:
.panel {
&.panel-parent .panel-child { //<=== Workaround
// .panel.panel-parent .panel-child{...}
}
.panel-child {
// some rules
}
}
}
推荐答案
同一元素的类顺序实际上并不重要,即.panel.panel-parent
等于.panel-parent.panel
(两者都匹配<div class="panel panel-parent">
),因此您只需使用即可获得所需的东西:
The order of classes of the same element does not actually matter, i.e. .panel.panel-parent
is equal to .panel-parent.panel
(both will match <div class="panel panel-parent">
), thus you can get what you need with just:
.panel {
.panel-child {
a: a;
.panel-parent& {
b: b;
}
}
}
相反.
