Aligning asp:radiobutton

add the following snippet on your css style sheet:

.radiobtn, input[type="radio"]
{
    font-size:12px; 
    line-height:14px;
    vertical-align:middle;
}
on your asp page, just do:
<asp:RadioButton ID="rbtnID" runat="server" Text="Option 1" GroupName="rbtnGroup" CssClass="radiobtn"/>

table-tr, ul-li, dl-dt may be used to perfectly align your radio button lists (i don't have any preference). Others suggest dl-dt is the best way to go.. i use table-tr for special cases.
