:ml-search-more[style lang="less"]是用于在HTML中启用Less预处理器的属性，允许直接在:ml-search-more[<style>标签]中编写Less代码并自动编译为CSS。
基本用法
在:ml-search-more[<style>标签]中添加lang="less"属性：
html
Copy Code
<style lang="less" scoped>
@color: red;
.box {
color: @color;
}
</style>
此代码会编译为标准CSS，@color变量会被替换为red。
注意事项
作用域：添加scoped属性时，Less变量和混合（mixin）的作用域会受限于当前组件，避免全局污染。
依赖安装：若项目未配置Less支持，需安装:ml-search-more[less-loader]和:ml-search-more[less]：
bash：
npm install less less-loader --save-dev
并在构建工具（如Webpack）中配置:ml-search-more[loader]规则。
兼容性：部分旧版框架可能需要额外配置（如:ml-search-more[Vue CLI]的:ml-search-more[style-resources-loader]）。
示例：
<style lang="less">
@primary-color: #007bff;
.button {
background-color: @primary-color;
&:hover {
background-color: darken(@primary-color, 10%);
}
}
</style>
编译后：
css
Copy Code
.button {
background-color: #007bff;
}
.button:hover {
background-color: #0069d9;
}
``` :ml-citation{ref="5,6" data="citationList"}
:::ml-data{name=citationList}
```json
