Why is not working?
Briefly

The issue with buttons not responding on the website is likely caused by overlapping elements from the circles animation, preventing interaction with the buttons.
The CSS for the circles is set to position them absolutely, which is causing them to cover the area where the button exists, making it unresponsive.
To fix the button interaction, consider changing the CSS for the circles or adjusting the z-index property to ensure buttons are clickable.
Review and test the layout adjustments; sometimes simple changes in CSS can resolve issues with overlapping elements.
