Definately the designing control and freedom offered by pure CSS can't be matched by either of frameworks but Tailwind also provides freedom to add design to a very good extent and have its own advantages over the vanilla CSS like :
Bootsrap works realy well when you don't much focus on the designing of UI portion and need elements to just arrange and test the woking moreover a similar sense of styling is used in bootstrap so a very less freedom is given to modify or redesign.
pre-requisite : nodejs should be installed , go to cmd or terminal of your code editor and run : node -v to confirm installation
Now you are rady to run Tailwind CSS.
