Checkout display is messed up

Hi

I have put my store up using the template that was already installed and when at the checkout page the layout has cut of the left side and pushed everything to the right. See picture.

Do I add custom CSS to fix this issue if so please advise what to do.

Thanks kindly

Dear Nicky,
