Transfer the whole codebase styling to tailwind css to maintain industry standards

[ItsRoy69]

As we can see the codebase, there are stylings done in different components and pages which are equally adjusted in with different classnames, now this makes unnecessary usage of codes and makes difficult to apply the changes in every components, now fix the css in such that the styling properties are distributed equally and dont need to repeat the codes everywhere.

Maintain industry coding standards, if having doubts, fix one page and ask for review as it needs proper detailing.
