Basic Usage Support

Hi,

I have a webform with a picture like this <img src="cofee.png" class="cofee" />

I've added a Form CSS mutation like this:
Form ID: "
webform-client-form-319"

Variant 1: show cofee
css class: "cofee"

Variant 2:hide cofee
css class: "cofee"
inline css: "display:none !important;width:1px !important"

It shows always the original content (located on http://mercadoforex.net/newsletter-mailchimp-form). I haven't set any condition.

Thanks!
