Thats my code. I just want add BootStrap styles to add to my html components I already read aloot tutorials but are complexive, i am new at Haskell. I Need a simples thing just to that simple project. Thank.s

You can add it in your Handler function like this:
getUsuarioR :: Handler Html
getUsuarioR = do
(widget, enctype) <- generateFormPost formUser
defaultLayout $ do
addStylesheetRemote "http://remote-bootstrap-path.css"
[whamlet|
<form method=post enctype=#{enctype} action=@{UsuarioR}>
^{widget}
<input type="submit" value="Enviar">
|]
Also if you are new to Haskell, I would suggest you to learn some minimal Haskell before diving into Yesod.
