How do I make the border line shorter? Options

[sparklz4jrt]

I have a quick question. You know how on your blogger, there are side modules that are seperated by a line? How do you make those lines smaller insted of going all the way across? I have to do this for class and I can't figure it out for the life of me. HELP!! We have to keep it with the CSS theme so only CSS code please! I have tried width, height, etc. I already have it as 1px wide, solid line and a color. I just cant figure out how to make the line shorter. HELP!!

Sorry I made a double post earlier. My bad.

But does anyone know this answer? Can anyone help me, please? This is due for my class tomorrow and I can't figure it out for the life of me. I tried several different thing such has moving the div, adding padding, etc. It still doesn't work. Can someone help me please?
