Try to remove line - and it shifts

I have this line running vertically down the left side of my box image.
See attachment: (box-issue1.jpg)
So, I try to fix it by changing the css widths (see code below) from 273 to 275,
but the line shifts to the right side of the box.
See attachment: (box-issue2.jpg).

Can you tell me how to remove this vertical line altogether?
Thanks. Here’s the css code:

td.qbox2_tl {
background:url(images/qbox2_tl.gif);
background-repeat:no-repeat;
background-position:top;
width:17px;
height:17px;
}

Hi,
We probably could if you can provide the html and the images that go with your CSS. It would be best to set up a live test case and give us a link, we can’t debug screenshots very well.

You are using a table for this object? Can you post the html?
