Website does not scale with a smaller window

Hello,

I’m having trouble understanding how to scale my website’s elements down. It looks perfect when maximised, but everything goes ham and out of place if the user restores down the browser window. Or uses a different size than full. I am definitely missing something here…

Thanks for any help I can get!
Sean.

I temporarily fixed the issue by making the elements smaller. And I think it looks better now anyway.

Case closed!
