list.skin.php에서 버튼 주위의 파란색 부분을 없앨려고 하는데 주의의 파란색 부분이 어디서

없애는지 알수가 없네요.

이미지 파일에서는 아닌것 같은데요.
아래부분에 소스 올려봅니다. 어떻게 수정해야 하는지 좀 부탁드립니다.

`<?
if (!defined("_GNUBOARD_")) exit; // 개별 페이지 접근 불가

// 선택옵션으로 인해 셀합치기가 가변적으로 변함
$colspan = 6;

//if ($is_category) $colspan++;
if ($is_checkbox) $colspan++;
if ($is_good) $colspan++;
if ($is_nogood) $colspan++;

// 제목이 두줄로 표시되는 경우 이 코드를 사용해 보세요.
// <nobr style='display:block; overflow:hidden; width:000px;'>제목</nobr>
