这是我的第一篇文章。当我悬停在导航栏中时，我遇到背景颜色问题。它在Mozilla中运行良好，但由于某种原因，在Chrome浏览器中，只有部分菜单项在悬停时发生变化。任何帮助将不胜感激。导航链接背景悬停在谷歌浏览器中不起作用
<?php
$link = mysql_connect ("localhost", "pouredin_web", "Asdfgh.12345") or die ('I cannot connect to the database.');
mysql_select_db("pouredin_web", $link);
//$Sql = "select * from news where status = 1 and web_id = ".$web_id." and pdate_in < NOW() and pdate_out > NOW() and ntype = 'Evento' order by nlevel, pdate_in desc limit 0,3 ";
$Sql = "select * from contents";
$data = array();
$result = mysql_query($Sql,$link);
while($row = mysql_fetch_array($result))
{
$data[$row["name"]] = $row["ntext"];
//echo $row["name"].'<br>';
}
mysql_free_result($result);
