Welcome, VirajKanse.

Hey there thanks for the response.
I fixed it few minutes ago, was trying to fix this since last 3-4 hours (╥﹏╥)

Here’s the fix,

#main-container {
    overflow: hidden;
}

Edit: there was another mistake that caused the issue I mistakenly set nav-bar anchor tag padding to 150px;
Reducing it work as well ಥ‿ಥ.
It must be typo like 15 ==> 150.
