}

為了在儲存時能夠，自動的修正錯誤，請在 vscode 中的 setting.json 請加入 => "source.fixAll.stylelint": true

"editor.codeActionsOnSave": {
    "source.fixAll.eslint": true,
    "source.fixAll.stylelint": true 
  },

VS Code 安裝 style lint plugin

此時你在開發專案中的 css 時，存檔就能自動幫你自動修正錯誤

如果你想套用在整個專案

終端機輸入以下指令

// 檢查錯誤
 npx stylelint "**/*.css"
// 修正錯誤
 npx stylelint "**/*.css" --fix

或是在 package.json 內設定，透過 npm run lint:style 去執行

/ package.json

{
  "scripts": {
    "check:style": "stylelint **/*.{css,scss,sass,vue}",
    "lint:style": "stylelint **/*.{css,scss,sass,vue} --fix"
  }
}
