Form CSS styling

Hi there,

I have applied a css style to both the the form and also to various form elements but the css is stripped away.

Is there any way to add CSS?

DEFAULT CSS - the default code without perch tags added.

<form class="uk-form">
<div class="uk-form-row">
        <label class="uk-form-label" for="form-s-ip">Name</label>
        <div class="uk-width-3-4">
        <input id="form-s-ip" type="text" placeholder="Text input">
        </div>
    </div>
</form>

PERCH TAGS - updated with perch tags

  <perch:form id="form-contact" class="uk-form" method="post" app="perch_forms">
<div class="uk-form-row">
        <perch:label for="name" class="uk-form-label">Name</perch:label>
        <div class="uk-width-3-4">
        <perch:input type="text" id="name" required="true" label="Name" />
        </div>
    </div>
</perch:form>

Thanks in advance. Alec
