我一直在寻找问题的答案，但似乎没有任何效果，所以希望这里有人可以帮助我。
我正在尝试将我的 SharePoint 网站的顶部导航菜单居中，但没有任何运气。我尝试在 NavMainBar 类下指定宽度、margin:0 auto 和 text-align=center 以及其他各种建议。无论我尝试什么，子站点（文本）总是左对齐。我确信它是次要的，但对于我的生活，我错过了一些东西。
附上一段CSS。希望有人能告诉我哪里出错了。
编辑：添加了一个屏幕转储，让自己更清楚我遇到的问题。我需要将菜单上子站点中的文本（即表单、信息路径、测试 1 等）移动到页面中间。基本上，仅将顶部导航菜单中的标题文本居中，而不是下拉菜单中的项目

/* Top Menu */
.NavMainBar {position:relative; width:100%; text-align:center; height:40px; padding-bottom:1px; border:0px solid #000;}
.NavBarIn {float:left; padding-left:10px; height:40px; }
.NavBarLeft {float:left; height:40px; width:9px; background-color:#EBEBEB; /*background-image:url('../../../Images/navBarLeft.png');*/ background-repeat:no-repeat;}
.NavBarRight {float:left; height:40px; width:9px; background-color:#EBEBEB; /*background-image:url('../../../Images/navBarRight.png'); */ background-repeat:no-repeat;}
.NavBarFill {float:left; width:98%; height:40px; background-color:#EBEBEB; /*background-image:url('../../../Images/navBarFill.png'); */ background-repeat:repeat-x;}
编辑：添加了 HTML - 对其他类的引用是对股票标准 core4v.css
