The image above shows check-boxes parallel to eachother vertically, however this is IE6 and shows a noticeable error compared to other browsers.
The check-box has spacing almost like a margin around the perimeter of the box itself, in other browsers this does not exist but if there is a fix I would like to do so.
How would I remove the margin or fix this error in IE6 and possibly other browsers?
EDIT
I want a permanent fix that is compliant with any browser.
If you’re not using a CSS reset stylesheet, you should. It will “reset” the default styles of browsers so you have a clean, identical slate to start with.
