I was searching for something to help me understand why this happens but I cannot find it , so I'm writing a new topic. My site looks different on other computers. But I mean - ugly different, the sections on the main menu are overlapped, the top part of the website doesn't look good - some lines are not connected, the fields are smaller, etc.
When I open my site on my computer-with 3 different browsers- everything looks good, exactly the way I did it, but when I open it from another PC - it's almost all wrong. ( By the way- I'm talking about laptops with almost the same size of monitor)
I wonder how it will look if someone has bigger monitor... 
Why is happening this? Are there some settings to make the site look the same way no matter the size of the monitor, no matter operating system, browser, no matter laptop or not?
