Here is a piece of code from the Announcement.ascx page
<portal:title EditText="Add New Announcement" EditUrl="~/DesktopModules/EditAnnouncements.aspx" runat="server" />
<asp:DataList id="myDataList" CellPadding="4" Width="98%" EnableViewState="false" runat="server">
<ItemTemplate>
<asp:HyperLink id="editLink" ImageUrl="~/images/edit.gif" NavigateUrl='<%# "~/DesktopModules/EditAnnouncements.aspx?ItemID=" + DataBinder.Eval(Container.DataItem,"ItemID") + "&mid=" + ModuleId %>' Visible="<%# IsEditable %>" runat="server" />
<span class="ItemTitle">
<%# DataBinder.Eval(Container.DataItem,"Title") %>
</span>
the css file is triggered in the '<span class="ItemTitle">' tag. If you open your *.css file (portal.css) and search for 'ItemTitle' you will see the formating that takes place.
