样式继承

一切都很简单。让人感到沮丧。昨天一切正常，今天打开电脑和Denver，访问网站时发现其中一个区块拒绝接受样式，Firebug显示没有为它定义样式，尽管三个相邻的区块使用相同的样式却正常工作。

以下是来自page.css的代码片段：

/*页脚菜单*/

#block-menu-menu-secondary-menu li.first.expanded.menu-depth-1.menu-item-740{

width: 200px;

float: left;

margin-left: 100px;

font-size: 12px;

}

#block-menu-menu-secondary-menu li.first.expanded.menu-depth-1.menu-item-740 a{

color: #888;

}

#block-menu-menu-secondary-menu li.first.expanded.menu-depth-1.menu-item-740 a:hover{

color: #E25401;

}

#block-menu-menu-secondary-menu li.expanded.menu-depth-1.menu-item-749{

width: 200px;

float: left;

margin-left: 80px;

font-size: 12px;

}

#block-menu-menu-secondary-menu li.expanded.menu-depth-1.menu-item-749 a{

color: #888;

}

#block-menu-menu-secondary-menu li.expanded.menu-depth-1.menu-item-749 a:hover{

color: #E25401;

}

 

#block-menu-menu-secondary-menu li.expanded.menu-depth-1.menu-item-745{

width: 200px;

float: left;

margin-left: 80px;

font-size: 12px;

}

#block-menu-menu-secondary-menu li.expanded.menu-depth-1.menu-item-745 a{

color: #888;

}

#block-menu-menu-secondary-menu li.expanded.menu-depth-1.menu-item-745 a:hover{

color: #E25401;

}

#block-menu-menu-secondary-menu li.last.expanded.menu-depth-1.menu-item-753{

width: 200px;

float: left;

margin-left: 80px;

font-size: 12px;

}

#block-menu-menu-secondary-menu li.last.expanded.menu-depth-1.menu-item-753 a{

color: #888;

}

#block-menu-menu-secondary-menu li.last.expanded.menu-depth-1.menu-item-753 a:hover{

color: #E25401;

}

#block-menu-menu-secondary-menu{

border-top: 1px dashed #afafaf;

}
