I have a repeater in my webpage, and I would like to change the background colors. First one will be blue, second yellow, then blue and so on.. I have the below table but do not know how to implement a javascript or css on the repeater. Can anyone assist?

```
            <asp:Repeater ID="cevapgoruntuleyici" runat="server"
                OnItemDataBound="cevapgoruntuleyici_ItemDataBound">
                <ItemTemplate>
                    <table width="693" border="1" cellpadding="0" cellspacing="0" bordercolor="#CCCCCC">
                        <tr>
                            <td colspan="2" class="style2">
                                <asp:Label ID="lblcevapno" runat="server"></asp:Label><br />
                                <br />
                                <asp:Label ID="lblcevapdetay" runat="server"></asp:Label></td>
                        </tr>
                        <tr>
                            <td width="344">
                                <asp:Label ID="lblcevaplayan" runat="server"></asp:Label>
                            </td>
                            <td width="343" class="style3">
                                <asp:Label ID="lblcevaptarih" runat="server"></asp:Label>
                            </td>
                            <tr>
                                <td>
                                    <asp:Label ID="CevapEk" Visible="false" runat="server" />
                                    <asp:Button ID="CevapEkIndir" Visible="false" runat="server" OnClick="CevapEkIndir_Click" />

                                </td>

                            </tr>
                        </tr>
                    </table>
                    <br />
                </ItemTemplate>
            </asp:Repeater>
