CSS div changes position on specific pages - html

Question

I'm having a strange CSS problem where the main div container on my website shifts to the right when I visit certain pages. This happens even though there is no specific CSS rule to move it
I've uploaded a temp version of my site here:
http://myawesometestsite.ddns.net/
When you go to the Publications and Contact page the entire container shifts to the right by a few pixels. The position appears to be correct and unshifted on all other pages
This is the full CSS I'm using:

I don't believe there's anything in here that's causing the container to shift for just those 2 pages but maybe I'm missing something. Anyone have any idea whats causing this?

Answer 1

Add "overflow-y: scroll;" to your "body" selector. It should look like this in your CSS:
body {
background-color: #dcd8cf;
font-family: Raleway, Arial, sans-serif;
font-size: 1em;
overflow-y: scroll;
}

Answer 2

The lenght of the pages create a vertical scroll bar. Publication and contact are small then the other are more big then the screen. for fix this you need an overflow-y set to scroll;
body {
overflow-y: scroll;
}
