Hi,

Find below the subscribe form code used in Catalog Demo:

<div class="row">
  <style scoped>
  .vu_mailchimp-form .vu_mcf-input {
        border: none !important;
          border-radius: 3px 0 0 3px;
          background-color: #fff;
      }
  .vu_mailchimp-form .vu_mcf-button {
        border-radius: 0 3px 3px 0;
    }
  .vu_mailchimp-form .vu_mcf-button:hover {
            opacity: 0.8;
            color: #fff;
          border-color: #ebb576;
        background-color: #ebb576 !important;
    }
 </style>
  
 <div class="col-xs-8 p-r-0">
 <input type="email" name="EMAIL" class="vu_mcf-input form-control" placeholder="Type here your email address" required />
 </div>
<div class="col-xs-4 p-l-0">
    <button type="submit" class="btn btn-inverse btn-primary btn-block vu_mcf-button">Sign Up</button>
 </div>
</div>

Kind regards,

You're welcome!
