How can I center my store pages on mobile and adjust heading font size?

Hi!
My store’s pages are off centre on mobile only. Is there a way I can change this? I have added in a code to centre it but it only worked for the desktop version of my store.
Also how can i change the font size of those headings to be a bit smaller?

thank you
