We set the width of our link to be “0”, to avoid the link getting thicker when we zoom in, but the clickable region for selecting the link is still very thick when we zoom in to a large scale. We have links layout very close each other, when we zoom in to a large scale, the clickable region of links are overlapped each other, we can not pick the link we really want to pick.

How do we set the clickable region of a link thinner, may be a few pixels width?
