我正在从 icon--apply 而不是 .classname__icon--apply 中选取我的图标颜色。这不违反 CSS 特异性规则吗？我在这里遗漏了什么吗？
最佳答案
您将 BEM 与特定性混淆了。
不要把特异性想成一套规则，它更像是一种机制。一种决定哪条规则应该比其他规则更重要的机制。
There's a whole bunch of selectors but for our purposes, we can break it down into three types, of increasing importance:
- Element selectors (and pseudo-element selectors) Eg. p {color:red;}
- Class selectors (and attribute selectors) Eg. .myclass {color:red;}
- ID selectors. Eg. #myid {color:red;}

BEM 是 CSS 类的命名约定。 您可以决定是否要使用它。这是可选的。
The Block, Element, Modifier methodology (commonly referred to as BEM) is a popular naming convention for classes in HTML and CSS. Developed by the team at Yandex, its goal is to help developers better understand the relationship between the HTML and CSS in a given project.

另一个命名约定是 Atomic CSS，您可以在其中使用许多小型的单一用途类 - 例如 .color-red。
