blocks? php nuke?
it will be in the "theme.php"
ex
public_html/themes/zabb/theme.php
there will be a section that looks like this.
PHP Code:
<?
function themesidebox($title, $content) {
global $nukeurl;
echo "<table border=\"0\" align=\"center\" width=\"150\" cellpadding=\"0\" cellspacing=\"1\" bgcolor=\"#990000\">"
."<tr><td width=\"100%\">"
."<table width=\"100%\" cellpadding=\"0\" cellspacing=\"0\"><tr><td width=\"100%\">"
."<table width=\"100%\" cellpadding=\"0\" cellspacing=\"0\"><tr><td background=\"$nukeurl/themes/Red/images/table-title.gif\" width=\"15\" height=\"23\">"
."<img src=\"$nukeurl/themes/Red/images/pip_table-title.gif\" border=\"0\" alt=\"\"></td>"
."<td background=\"$nukeurl/themes/Red/images/table-title.gif\" width=\"100%\" height=\"23\"><font color=\"#FFFFFF\"><b>$title</b></font>"
."</td></tr></table></td</tr><tr><td width=\"100%\" bgcolor=\"#000000\">"
."<table border=\"0\" cellpadding=\"2\" cellspacing=\"1\" width=\"100%\" align=\"center\">"
."<tr><td width=\"100%\" bgcolor=\"#990000\">"
."$content"
."</td></tr>"
."<tr><td background=\"$nukeurl/themes/Red/images/tablebottom.gif\" width=\"15\" height=\"15\">"
."</td></tr></table></td></tr></table></td></td></tr></table><br />";
}
?>
in that text the "000000" is the background color and the "990000 is for the block header and the bottom 1 is for the footer of the block.
that is code out of a almost stock nuke theme.
remember to back up all files before editing them.
hoope that helps
