Tip
ElementPlus v2.2.0 already supports dark mode, You only need to follow the Dark Mode to control the two component library colors.
css-variables is recommended
:root {
--el-color-primary: #42b983;
--pro-layout-aside-background-color: #f0f2f5;
}
Only need to configure the dark mode of ElementPlus
import 'element-plus/theme-chalk/dark/css-vars.css'
<html class="dark"></html>
:root {
--el-color-primary: #42b983;
--pro-layout-aside-background-color: #f0f2f5;
}
html.my {
--el-color-primary: #25272a;
--pro-layout-aside-background-color: #2b2b2b;
}
html.other {
/* ... */
}
<html class="other"></html>
Tip
Then you can dynamically change the value of class through js
Use postcss-custom-properties or similar plugin of postcss to convert css-variables for better compatibility, so that the default value style can be displayed when css-variables is not supported.
