how can i align the submit button of a form to center?
Sometimes centering objects with CSS can be tricky. If you are having trouble you can always try enclosing the button code in <center></center> tags. These days this is kind of a hack method, but many times it works much easier this way.
With CSS, not with HTML like your tag says. https://www.w3schools.com/css/css_align.asp
