Style radio buttons symfony - radiobuttonlist

Question

I'm trying to style some radio buttons that are in a list but when I declare input["type=radio"]{ border-style: none; } in the CSS file it does nothing.
Here is the code where the radio buttons are:
<?php echo $form['servico_id']; ?>.
The servico_id is a list with six radio buttons options from the form new.
Can you help me? I hope I've explained myself well.
Thank you
the form newSuccess:
<form action="<?php echo url_for('marcacao/'.($form->getObject()->isNew() ? 'create' : 'update').(!$form->getObject()->isNew() ? '?id='.$form->getObject()->getId() : '')) ?>" method="post" <?php $form->isMultipart() and print 'enctype="multipart/form-data" ' ?>>
<?php if (!$form->getObject()->isNew()): ?>
<input type="hidden" name="sf_method" value="put" />
<?php endif; ?>
<div id="sub-titulo">Dados Pessoais</div>
<div class="sombra">Nome
<?php echo $form['nome']; ?>
<?php echo $form['id']; ?>
<?php echo $form['_csrf_token']; ?>
</div>
<div class="sombra">E-mail
<?php echo $form['email']; ?>
</div>
<div class="sombra">Contacto
<?php echo $form['contacto']; ?>
</div>
<div id="sub-titulo">Preferência Horária</div>
<div class="sombra"> Dia<?php echo $form['dia']; ?> Hora<?php echo $form['hora']; ?></div>
<div id="sub-titulo">Serviços</div>
<?php echo $form['servico_id']; ?>
<input type="submit" name="submit" value="Marcar >"/>
</form>
</div>

Answer 1

It looks as though you are putting JQuery selector syntax in your css file. This is not
correct. Instead either tag your input type="radio" elements with a CSS class and style that class in your css file, or add a javascript block to style your elements using jQuery.
ie. CSS file:
input.radio {
background-color: blue; //style as you wish
}
ie. HTML:
<input type="radio" class="radio" /> Yes
<input type="radio" class="radio" /> No
Or the alternative way (using JQuery/Javascript):
<script type="text/javascript">
$(function() {
$("input:radio").css('background-color', 'blue);
});
</script>

You could handle it with symfony like this :
Give your radio input a css class within the symfony form configure() function
$this->widgetSchema["myradio"]->setAttribute("class" => "mySpecialRadio");
Put your styling in corresponding css file
/* If you use ul/li rendering of sfWidgetFormChoice */
li.mySpecialRadio {
color: red;
}
input[type="radio"].mySpecialRadio {
float: right;
}
