【Docker + Rails6系 + TailwindCSSバージョン2】JITモードが機能していない(使えない)
概要
tailwindcssバージョン2を使用しており、tailwind.config.jsファイルに「mode: "jit"」を追加したがjitモードが使えません。
発生している問題
jitモードをONにしていると、「w-[540px]」といったこともできるとドキュメントに記載されていたので試してみましたが、できませんでした。
tailwindをインストールした最初の段階で、tailwind.config.js「mode: "jit"」は追加していたので、何が原因かわかりません。
tailwind.config.js
module.exports = {
mode: "jit",
purge: [
"./app/views/**/*.html.erb",
"./app/helpers/**/*.rb",
"./app/javascript/**/*.js",
],
darkMode: false, // or 'media' or 'class'
theme: {
extend: {},
},
},
variants: {
extend: {},
},
plugins: [],
};
