@include和@extend之间的东西与sass [英] Something between @include and @extend with sass

问题描述

是否可以在sass中包含css规则而不重复代码？
随着扩展我们正在扩展代码，但我不想要那个eiter。我想要包含它，不需要重复代码。

Is it possible to include a css rule in sass without duplicate the code? With extend we are extending the code, but i dont want that eiter. I want include it, without duplicating code.

对于示例

SCSS：

.heading {
    font-size: 16px;
    font-family: my-cool-font;
}

.box {
    background: red;
    h1 {
        @extend .heading;
        color: white;
    }
}

.my-other-box {
    .heading {
        color: black;
    }
}

HTML

<div class="box">
   <h1>My heading</h1>
</div>
<div class="my-other-box">
   <h1 class="heading">My heading</h1>
</div>

CSS

.heading, .box h1 {
    font-size: 16px;
    font-family: my-cool-font;
}
.box {
    background: red;
 }
.box h1 {
    color: white;
}

.my-other-box .heading,
.my-other-box .box h1,
.box .my-other-box h1 {
    color: black;
}

所以最后两条规则是因为它的延伸（我理解的好处是它）。
但是如果我想要使用类，并且扩展我不希望它扩展，只需包含它。但我不希望它复制代码。

So the two last rules there are because its extending (I understand the benifits of it). But if i want to both use classes, and extends i dont want it to extend, just include it. But i dont want it to duplicate the code.

我想：

CSS

.heading, .box h1 {
    font-size: 16px;
    font-family: my-cool-font;
}
.box {
    background: red;
 }
.box h1 {
    color: white;
}

.my-other-box .heading {
    color: black;
}

推荐答案

如果你使用扩展类（或使用与您在其他地方重复的类名称不同的类名称），您可以获得您正在寻找的输出：

If you use an extend class (or use a class name that differs from one you're repeating elsewhere), you can get the output you're looking for:

%heading, .heading {
    font-size: 16px;
    font-family: my-cool-font;
}

.box {
    background: red;
    h1 {
        @extend %heading;
        color: white;
    }
}

.my-other-box {
    .heading {
        color: black;
    }
}

输出：

.box h1, .heading {
  font-size: 16px;
  font-family: my-cool-font;
}

.box {
  background: red;
}

.box h1 {
  color: white;
}

.my-other-box .heading {
  color: black;
}
