Answer 1

So,I try to use this in asp.net

 <div class="col-sm-8">
     <asp:RadioButtonList ID="rblHalfday" runat="server" Visible="false" RepeatDirection="Horizontal" RepeatLayout="Table" RepeatColumns="2" CssClass="mylist">
        <asp:ListItem Text="First Half" Value="1" />
        <asp:ListItem Text="Second Half" Value="2" />
        </asp:RadioButtonList>
 </div>

and this is the css

 table.mylist label {
      width: 100px;
      display: block;
      float: left;
      margin-left: 20px;
      margin-right: 5px;
   }

And the text in line like image below. BUT I want the text inline with the radio button too.

This is what I got:
