[CSS][HTML] Whitespace around image

Hello, I got weird problem with my edit button. I have in my table cell edit image as link, but when I add <a href = ..> then I got whitespace around the image (however image displays well without it).
I tried many fixes on net, but no one want to work. It looks like this:
Attachment 661

PHP Code:

---

echo "...
<table width="100%" cellpadding="1" cellspacing="1" border="0" class="forumline">
....
<tr>... <td><a href=\"http://myextreme.pl/admin_panel.php?type=access_management&edit_$results[id]\"><img src= \"img/edit.png\" alt=\"edit\"></a></td>....</tr>
....
</table>";

CSS:
.forumline{background-color: #161616;border: 0px; }

How can I add image as link in table cell without this white space around? Thanks in advice.

Easiest is to check the CSS attributies with Firefox (Firebird plugin) or Chrome by just pressing F12, to open the Inspector, and then you can click on the element to see the CSS attributes.

I guess there is just some "old" CSS code, which is applied to many elements and which rule you don't want on the a-tag anymore (so just overwrite it after you found it with Firebug).

This video is a good introduction:

Oh.. I fixed it. It was really my mistake. I was using my old .css which has something like

#content a{background:#fff; ... }

which was inadvertently omitted by me :cool:

Thanks you Kung, because F12 told me everything ;)
