LESS CSS嵌套类 [英] LESS CSS nesting classes

问题描述

我使用LESS来改进我的CSS，并试图在类中嵌套一个类。有一个相当复杂的层次结构，但由于某种原因，我的嵌套不工作。
我有这个：

I'm using LESS to improve my CSS and am trying to nest a class within a class. There's a fairly complicated hierarchy but for some reason my nesting doesn't work. I have this:

.g {
    float: left;
    color: #323a13;
    .border(1px,#afc945);
    .gradient(#afc945, #c8da64);
    .common;
    span {
        .my-span;
        .border-dashed(1px,rgba(255,255,255,0.3));
    }
    .posted {
         .my-posted;
         span {
            border: none;
         }
    }
}

.g.posted 工作。它只是显示 .g 位。
如果我这样做很好：

I can't get the .g.posted to work. it just shows the .g bit. If i do this it's fine:

.g {
    float: left;
    color: #323a13;
    .border(1px,#afc945);
    .gradient(#afc945, #c8da64);
    .common;
    span {
        .my-span;
        .border-dashed(1px,rgba(255,255,255,0.3));
    }
}

.g.posted {
         .my-posted;
         span {
            border: none;
         }
    }

我想嵌套 .posted 在 .g 。任何想法？

I'd like to nest the .posted in .g though. Any ideas?

推荐答案

LESS不工作。

.class1.class2 {} - 在同一个DOM节点上定义两个类，但

.class1.class2 {} - defines two classes on the same DOM node, but

.class1 {
    .class2 {}
}

定义嵌套节点。 .class2 仅适用于 class1 的节点的子节点。

defines nested nodes. .class2 will only be applied if it is a child of a node with the class class1.

我也对此感到困惑，我的结论是LESS需要一个这个关键字：）。

I've been confused with this too and my conclusion is that LESS needs a this keyword :).

由于我没有任何评论或论证，我感到不得不对我的感觉作出反应

As I have been downvoted without any comment or justification, I feel obliged to react to what I feel like might be the cause of the downvote.

& 字符具有这个关键字，实际上（一个我在写答案的时候不知道的东西）。可以写成：

The & character has the function of a this keyword, actually (a thing I did not know at the moment of writing the answer). It is possible to write:

.class1 {
    &.class2 {}
}

，生成的CSS将如下所示：

and the generated CSS will look like this:

.class.class2 {}
