Changing the navbar styling and social icons alignement in about page

[naveengitboi]

Which feature you are going to add

The background effect and box-shadow effects on nav links are not that effective and takes all the appeal of the good-looking website.

Describe the solution you'd like

I will remove that background and box-shadow effect on nav links and I Will keep only that after-effect (Underlined in yellow thing) which looks cool for this site.
