WordPress site looks funky on iPad and Android

[Malcolm]

I've been studying elementor and made a pretty good site but it looks good on the computer but it looks weird on the iPad and Android phone. one of the pages doesn't show up at all except on the computer.
I'm using the free version of elementor and I use the astra theme.
Any suggestions?
My site is the same as my name with a.com at the end.
Thank Malcolm hathorne
