Button Not Centering on Mobile No Matter What CSS Code I Use

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

Hi! I'm brand new to Squarespace and a total rookie. I was able to remove the redundant Site Title from my Home Page via CSS code (yay!), but I can't for the life of me get my Contact Button ("Let's Make Something Together") to center on mobile view. I've copied and pasted so many different CSS codes from this forum to no avail. What am I missing? Thanks in advance! 

Hey @LesFen 👋

Are you using the new Fluid Engine by chance? Check to see if you can move it on the mobile's editing side. I did an inspect and it looks like the alignment might be caused by the grid layout set for the page in settings.

If that doesn't help, DM and we can try to take a look.
