title: the centering of the body/maindiv disappears when resizing the window smaller
body: <p>Hello i have a small css problem... just can´t figure it out, and i have already googled it, so; i have a main div, with divs in it and my thought is that when it opens om a smaller screen the divs should appear under each other, and it does.. my problem is that on a computer screen it is centered in the window, but as soon i resize the window so the first divs "jumps" to the next row, it seems like the centering disappears and it it stuck to the left side again..... please help... i want the divs to always be centered!</p>
