 HERE, WE NEED TO REFRESH THE PAGE AGAIN AND AGAIN TO SEE IF THE STYLING IS ADDED. HENCE, WE INSTALL VITE HERE.( WE'VE INSTALLED DURING REACT) HRE, WE WILL DOWNLOAD THE VERSION V3.4.17 TO INSTALL:  npm install -D tailwindcss@3 npx tailwindcss init -p WE ADD A FLAG -p   TO DOWNLOAD POSTCSS.CONFIG.JS DOWNLOAD VITE : npm i vite IN TAILWIND.CONFIG.JS , content:["*"] WHICH MEANS THAT TAILWIND IS APPLIED FOR ALL(*) THE FILES.HERE, WE CAN DEFINE THE FILES THAT WE WANT TAILWIND TO BE APPLIED FOR. WE CREATE A CSS FILE, AND ADD THESE LINES. @tailwind base ; @tailwind components ; @tailwind utilities ; IN PACKAGE.JSON    "scripts" : {     "start" : "vite"   }, NOW, LINK CSS WITH HTML.

SOMETIMES, WE MIGHT GET CONFUSED BY THE CLASS NAMES WHILE DEALING WITH LARGE CODE BASES. - BUNDLE SIZE  THE FINAL BUNDLE SIZE OF THE FILE IS NOT SIGNIFICANTLY INCREASED. BUNDLE SIZE REFERS TO THE FINAL CSS FILES THAT CONSISTS DATA ABOUT STYLING FOR EXAMPLE, IF WE'VE USED ONLY MARGIN AND PADDING CLASSES IN OUR FILES.
