Keeping blocks together on different screen sizes

Hi everyone

I am looking for something (I assume CSS code) that will keep blocks together at the same size across all browsers and screen sizes. 

If I view my site on a large monitor there is less (or more) space between different elements like text blocks and images across all my pages.   I am looking for a way to keep the blocks at the same space between each other no matter the end client screen resolution. 

Does this make sense and is there any solution?

Thanks in advance!

Anyone have an idea how to fix this issue?
