【Docker + Rails6系 + TailwindCSSバージョン2】tailwind.config.jsファイルでheightをカスタマイズしたが反映されない
概要
Docker + Rails6系 + TailwindCSSバージョン2でアプリを作成しているのですが、カスタマイズしたheightを使用したくてtailwind.config.jsファイルを変更しました。
しかし、カスタマイズしたheightは反映されませんでした。
発生している問題
400pxというオリジナルサイズのheightをカスタマイズするため、tailwind.config.jsファイルを以下のように編集しました。
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: {
height: {
400: "400px",
},
},
},
variants: {
extend: {},
},
plugins: [],
};
上記のように変更しただけでは、「h-400」とクラスを追加しても反映されなかったので、docker-compose downをしてからdocker-compose up -dをしました。
しかし、それでも「h-400」(height: 400px)は適用されませんでした。
何が問題なのかご教授いただけると嬉しいです泣
追記：JITモードも機能していないようなので、合わせて原因の究明ができると嬉しいです。
