Change CSS Font Size and Make Font bold in ASP.Net DropDownList

<style type = "text/css">
        .DropDown
        {
            font-weight:bold;
            font-size: 12pt;
        }
    </style>
    <asp:DropDownList ID = "ddl" runat = "server" CssClass = "DropDown">
    <asp:ListItem Text = "One" Value = "1" />
    <asp:ListItem Text = "Two" Value = "2" />
    <asp:ListItem Text = "Three" Value = "3" />
    </asp:DropDownList>

i did that before

and i bind my dropdown list from database

css class

   
  .DPCDDL
  {
     float:left;
         width:200px;
          height:20px;
          margin-top:1px;
           font:bold 12px Tahoma;
           
           }

<asp:DropDownList ID="DDL1" runat="server" CssClass="DPCDDL">
            </asp:DropDownList>

but it just bold selected item not all item that are in dropdownlist

Have you tried what I gave. It works fine for me

it didn't bold all item it just did font size to all item

but just selected item was bold

Font Bold will not work in IE as it does not support it for DropDown Items
