菜单不是中心对齐的

Question

您正在使用从数据库获取动态菜单的网站。我的问题是菜单不是中心对齐的。它只显示在它的托管div的左上角。以下是代码：

<div class="row">
                <div class="col-md-2 col-lg-2 col-sm-2 col-xs-12">
                    <asp:Image ID="Image1" runat="server" ImageUrl="~/images/offerboxindialogo9.png" class="img img-responsive"/>
                </div>
                <div class="col-md-8 col-lg-8 col-sm-8 col-xs-12">
                    <div class="navbar">
                        <asp:Menu ID="NavigationMenu" runat="server" class="mymenu" DynamicHorizontalOffset="2" Font-Bold="True" Font-Names="Verdana" 
                                        Font-Size="Smaller" ForeColor="white" Orientation="Horizontal" StaticSubMenuIndent="10px" 
                                        StaticEnableDefaultPopOutImage="false" DynamicEnableDefaultPopOutImage="false" 
                                        RenderingMode="List" Width="100%">
                                        <DataBindings>
                                            <asp:MenuItemBinding DataMember="Item" NavigateUrlField="url" TextField="Text" ValueField="Value" />
                                            <asp:MenuItemBinding DataMember="SubItem" NavigateUrlField="url" TextField="Text" ValueField="Value" />
                                        </DataBindings>
                                        <DynamicHoverStyle BackColor="purple" ForeColor="White" />
                                        <DynamicMenuItemStyle HorizontalPadding="10px" VerticalPadding="10px" ForeColor="purple" BackColor="White"/>
                                        <DynamicMenuStyle BorderWidth="2px" BorderColor="#990000" ForeColor="purple" />
                                        <DynamicSelectedStyle BackColor="#FFCC66" />
                                        <StaticHoverStyle BackColor="purple" ForeColor="White" CssClass="hoverstyle" />
                                        <StaticMenuItemStyle HorizontalPadding="10px" VerticalPadding="10px" />
                                        <StaticSelectedStyle BackColor="#FFCC66" />
                        </asp:Menu>
                    </div>
                </div>
                <div class="col-md-2 col-lg-2 col-sm-2 col-xs-12">
    </div>
</div>

我已尝试过css中的所有内容，包括float：none，display：inline，Center标记，vertical-align：middle，甚至尝试使用以下我在堆栈溢出的类似帖子中作为答案：

.mymenu>ul>li>a
{
    line-height: 50px;
}

也试过了     .mymenu ul li a     {         line-height：50px;     } 并尝试过     .mymenu + ul + li a     {         line-height：50px;     } 但没有什么能完美的。这三次尝试中的第一次尝试的问题是它也影响了下拉菜单项。
