sass 多个主题的角度 [英] sass multiple themes in angular
问题描述
假设我在一个 Angular 应用程序中有两个主题(浅色和深色)> 2,以及一个已配置为将主题类添加到 body 标签的切换按钮
Let's say I have two themes (light & dark) in an angular app > 2, and a toggle button which is already configured to add the theme class to the body tag
变量.scss
$themes: (
light: (
backgroundColor: #fff,
textColor: #408bbd,
borderColor: #254fe5,
),
dark: (
backgroundColor: #222,
textColor: #ddd,
borderColor: #2e4dd2,
),
);
I tried different approaches I found (here and here), but none worked.
我也尝试过最简单的方法
I also tried the simplest approach
about.component.scss
about.component.scss
.theme-dark .page-title{
color: white;
}
.theme-light .page-title{
color: red;
}
我知道 body 标签上的 .theme-dark
类无法从组件样式中识别出来,但我找不到任何解决方案.
I know the class .theme-dark
on body tag is not recognized from a component style, but I can't find any solution.
我可以使用什么方法在这样的模块系统中获得多个主题?
What approach can I use to get multiple themes in such modules system?
