1、定義variables.scss檔案

// base color
$blue:#324157;
$light-blue:#3A71A8;
$red:#C03639;
$pink: #E65D6E;
$green: #30B08F;
$tiffany: #4AB7BD;
$yellow:#FEC171;
$panGreen: #30B08F;


// 預設選單主題風格
$base-menu-color:#bfcbd9;
$base-menu-color-active:#f4f4f5;
$base-menu-background:#304156;
$base-logo-title-color: #ffffff;


// 用於程式碼中呼叫
:export 
 
{
  menuColor: $base-menu-color;
  menuLightColor: $base-menu-light-color;
  menuColorActive: $base-menu-color-active;
  menuBackground: $base-menu-background;
  menuLightBackground: $base-menu-light-background;
  menuLightBackgroundMy: $base-menu-light-background-my;
  subMenuBackground: $base-sub-menu-background
 
;
  subMenuHover: $base-sub-menu-hover;
  sideBarWidth: $base-sidebar-width;
  logoTitleColor: $base-logo-title-color;
  logoLightTitleColor: $base-logo-light-title-color
}

2、在<style>標籤中呼叫

<style lang="scss" scoped>
@import "~@/assets/styles/variables.scss";

.fixed-header {
  position: fixed
 
;
  top: 0;
  right: 0;
  z-index: 9;
  width: calc(100% - #{$base-sidebar-width});
  transition: width 0.28s;
}

.tools-wrap-hidden{
  z-index: 1;
  position: absolute;
  left: $base-sidebar-width + 10;
  top: 4em;
  display: flex;
  flex-direction: column;
}

</style>

3、在其他css檔案中呼叫方式

@import './variables.scss';

4、在程式碼中呼叫方式

<div  :style="{ backgroundColor: settings.sideTheme === 'theme-dark' ? variables.menuBackground : variables.menuLightBackgroundMy }">

<script>
import variables from "@/assets/styles/variables.scss";

export default {
    computed: {
         variables() {
            return variables;
        },
    }
}
</script>
