Styling a repeater inside a datalist

i've used a DataList (dlparent) control for one of my page. Inside that datalist is another Datalist (dlchild) that is being populated by itemdatabound event of the parent datalist. i've used css with dlchild.

Dat开发者_如何学Goabinding is ok and the required output shows great with mozilla and IE but not in netscape, safari and google chrome. dlchild is not showing. only item in dlparent appears.

Here's the markup for the dlparent:

<asp:DataList ID="SprintsWorkData" Style="float: left; padding-top: 10px;" runat="server"
        OnItemDataBound="SprintsWorkData_ItemDataBound">
        <ItemTemplate>
            <asp:HiddenField ID="hiddenSprintId" runat="server" Value='<%# Eval("SprintId") %>' />
            <div id="SprintNameSection">
                <h4>
                    <%# Eval("SprintName") %></h4>
            </div>
            <div id="HeaderSection_SelectAll">
                <div style="padding-top: 3px; height: 23px; padding-left: 2px;">

I've just forgot to add float:left to the inner datalist or dlchild. the parent datalist has float:left
