I want to apply for styles to @Html.EditorForModel(). Here is code snippet
@using (Html.BeginForm("LogOn", "Account", new { area = "", returnUrl = returnUrl }, FormMethod.Post)) {
using (Html.BtFieldset(Loc("legend", "Credentials"))) {
@Html.EditorForModel()
<div class="col-md-offset-4">
@Button.Submit(ViewResources.Action_Common_Logon)
</div>
}
