How to modify the line width of ipython notebook markdown cell

Question

I use ipython notebook to keep my diary using the markdown cell. The problem is that The linewidth of the cell is a little too wide, not very fine looking as a blog. The question is: how can I decrease the width of the line and keep it stay in the middle(or left) of the page?
