@sruti2024 @SaiSudhaV @PROTechThor Need Review for this PR 📝

[SaiSudhaV]

@Aryamanz29 There are some files that still have inline styling. Can't they be moved to an external file?

[Aryamanz29]

@SaiSudhaV Thanks for pointing it out. We can't move those inline styling because that creates a mess or may they overwrite the existing CSS, also if any chance I could move them to the external file they need proper Classes & ID names for specific HTML element and that's very hard for me to do because those designs aren't implemented by me (Also most of the CSS stylings in the is project directly copy from other sites that's why they even don't have classes and ID's).

P.S: In the future, if those inline CSS creates any kind of problem we can create a new issue for that.
