Look of website

Hi. I am really new to this and I am not very experienced in technical issues. I created my website and on my laptop it looks fine but when i looked at it today on my husbands laptop it looks terrible. Its not how I am seeing it on mine. i have checked it on my phone and again it looks terrible. its all out of order and the graphics are all wrong. i have no idea what has gone wrong. and I cant work out how to fix it? Can anyone help me please? Thank you
