Padding adjustment section does not appear

Site URL: https://www.vincerojp.com

Hello.

I am a beginner.
I am seeing a lot of gaps on the right side in mobile view; adjusting the padding seems to help, but I don't see the padding adjustment section in Design > Site Styles > Buttons panel.

Any advice on where I should check or what steps to take would be appreciated.

Site looks fine on me. Can you share link to page where you have the gap?

Thank you for your comment. Sorry for the delay in replying.

The URL is as follows
It will display on mobile, but there will be a gap on the right side.

Try adding to Design > Custom CSS

html, body {overflow-x:hidden;}
