Hi,

We suggest you to install our theme with all dummy content if you want to have a similar website with the same content. But if you want, you can manually create an HTML Block for the promo popup only. Here is a code for this block from our demo

<div class="vc_row">
<div class="vc_column_container vc_col-sm-6">
<div class="vc_column-inner ">
<figure style="margin: -20px;"><img src="http://placehold.it/760x800" /></figure>
</div>
</div>
<div class="vc_column_container vc_col-sm-6">
<div style="padding: 70px 25px 70px 40px;">
<h1 style="margin-bottom: 0px; text-align: center;"><strong>HELLO USER, JOIN OUR</strong></h1>
<h1 style="text-align: center;"><strong>NEWSLETTER<span style="color: #0f8a7e;"> BASEL & CO.</span></strong></h1>
<p style="text-align: center; font-size: 16px;">Be the first to learn about our latest trends and get exclusive offers.</p>
