编程式办法的益处
1.全局管制，防止款式散乱
2.代码简洁，开发疾速 函数式编程大量应用函数，缩小了代码的反复，因而程序比拟短，开发速度较快
3.靠近自然语言，易于了解 函数式编程的自由度很高，能够写出很靠近自然语言的代码
4.更不便的代码治理
5.书写款式成为一门艺术

.card-title { font: "PingFang-SC-medium"; color: #333; font-size: 18px;}.card-title { font: "PingFang-SC-regular"; font-size: 14px; color: #333;}Good
// 申明less函数.mixin-font-class(@fontColor: yellow; @fontSize; @fontFamily) { font-family: @fontFamily; font-size: @fontSize; color: @fontColor;}利用
h6 { .mixin-font-class(@fontColor:red;@fontSize:12px;@fontFamily:"PingFang-SC-medium");}h2{ .mixin-font-class(@fontColor:blue;@fontSize:15px;@fontFamily:"PingFang-SC-regular");}全局Less
在Vue-cli模式中
// 增加全局lesspluginOptions: { 'style-resources-loader': { preProcessor: 'less', patterns: [ resolve('./src/less/theme.less') ] }},// 在任何组件中或者less文件中应用<style lang="less" scoped>.breadTop { height: 60px; display: flex; align-items: center; justify-content: space-between; padding-right: 15px; h6 { .mixin-font-class(@fontColor:red;@fontSize:12px;@fontFamily:"PingFang-SC-medium"); } h2{ .mixin-font-class(@fontColor:blue;@fontSize:15px;@fontFamily:"PingFang-SC-regular"); }}</style>scss
$font-normal-color = #222;$font-light-color = #333;@mixin font-class($fontFamily, $fontSize, $fontColor) { font-family: $fontFamily; font-size: $fontSize; color: $fontColor;}@mixin font-large($size: 14px, $color: $font-normal-color) { @include font-class($font-family-medium, $size, $color);}@mixin font-normal($size: 14px, $color: $font-light-color) { @include font-class($font-family-regular, $size, $color);}应用
.form-title { @include font-large(16px, red);}.form-text { @include font-large(12px, blue);}留神less函数的参数应用的@，scss应用的$
