[HTML/CSS] Adding a vertical scroll changes the div size

[Magically]

Hello, second post

 

Ok, so I am finally working on a portfolio for my web development and photography, I have the first page done [un-responsive, will work on that at the end] and I am now working on the second page. 

The second page will contain the information about my web development, I will have a small paragraph and than my work underneath, how ever it will need a scroll bar to be viewed fully. 

Now I know how to add a scrollbar etc but when I do I find that my div re-sizes,

 

 

 

 

Free hugs and kisses to who ever helps me fix this, 

I have tried setting a min-width and min-height and the div is already positioned absolute.

 

Thanks!

Issue has been resolved, I moved the scrollbar onto the whole page as in onto the container which looks better and works fine.

overflow-y:scroll; ?
