Hello,

Thank you for your answer. Unfortunately, this css overload does not modify the button in question. And if I put 360 px instead of 320 px, the button is enlarged on the right and is not centered.

Overriding css to fix this issue is definitely not the right solution. Indeed, on this page of 9 buttons, 8 buttons are correct, only one is not. Obviously the solution is to be found in the settings of SP Page Builder.

By checking all the parameters one by one, I found my error on the margins and the problem is now solved.

Regards
