: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}
