Update Back to Top Button Visibility

[Devmoni]

Description

This PR updates the visibility behavior of the 'Back to Top' button. Instead of being only in the footer, the button now appears when the user scrolls down the page by 30%. This change improves the user experience by providing quicker access to the top of the page.

Is this feature also available in later versions of Bootstrap and Airspace? If so would it be better to upgrade?

[Devmoni]

This feature is implemented using only JavaScript and simple CSS, ensuring that it does not alter any core CSS of Bootstrap and Airspace.

I believe this can be useful since the site is quite long, helping users reach the top with just one click.

You didn't answer my question. I've checked, and I can find nothing in either Bootstrap or Airspace latest releases to indicate that the feature is provided by either library.

[Devmoni]

You're correct that Bootstrap and Airspace don't offer this feature by default.

But as for whether it would be better to upgrade,
Currently, the 'Return to Top' button is placed in the footer, but positioning it as a fixed button in the bottom-right corner would make it more accessible as users scroll.
A fixed button provides immediate visibility and usability, allowing users to return to the top without needing to scroll back down to the footer
