Home page looks messed up on different computer

So I’m running into this problem where my homepage looks messed up on my work computer, but doesn’t on my home computer and I’m not quite sure why. I don’t know if it is the screen resolution or what. The website is http://www.tmmslynn.com. If this is the problem and it is a screen resolution issue is there anything i can do to make sure no matter what the resolution my page looks the same?

Thank you in advance for any and all help.
