[英]Reusing styles in SASS/SCSS without merging selectors
If I have a style definition in SCSS that looks like this:如果我在 SCSS 中有一个如下所示的样式定义:
#someid {
...
.message {
...
&.error {
// overrides of .message class
}
}
}
So I display some kind of messages in my UI which can be normal message (have .message
class) or errors (have both .message.error
classes).所以我在我的 UI 中显示某种消息,它们可以是普通消息(具有
.message
类)或错误(具有.message.error
类)。
Now I have a different element that displays similar info in normal an erroneous way, that's why I would like to replicate error settings.现在我有一个不同的元素,它以正常和错误的方式显示类似的信息,这就是我想复制错误设置的原因。
How do I use @extend directive without putting styles in a separate class and then extending/using it in both .error
styles or using a mixin for the same purpose?如何使用 @extend 指令而不将样式放在单独的类中,然后在
.error
样式中扩展/使用它,或者出于相同目的使用 mixin? I would just like to reuse the same style definition.我只想重用相同的样式定义。
The problem is that it combines all kinds of class inheritance when I do an @extend
.问题在于,当我执行
@extend
时,它结合了各种类继承。
#otherid {
...
.notification {
...
&.error {
// should use the other ".error" style
}
}
}
The problem is that the compiled results has this style definition which is a mix and match of merged selectors:问题是编译结果具有这种样式定义,它是合并选择器的混合和匹配:
#someid .message.error,
#someid #otherid .message.notification.error,
#otherid #someid .message.notification.error
While I would rather have just these two:虽然我宁愿只有这两个:
#someid .message.error,
#otherid .notification.error
Could you use a @mixin?你能用@mixin吗?
// Define here
@mixin generic-error {
// Error styling
}
// Replace original
.notification {
&.error {
@include generic-error;
}
}
%some-css {
//CSS goes here.
}
.another-class {
@extend %some-css;
}
