How to reference data-section-id in the Brooklyn Theme?

[Deebella]

How do I reference the data-section-id? I know how to modify the shopify-content-id but I don't wont the whole section changed. I want to change the top margin associated with the header for only the section shown below. When I use "#shopify-content....." it modifies the all custom content added. site: curlsforthegurlls.com (no password) This change will apply only to the mobile side.

<div class="rte" data-section-id="163564723658ab831f" data-section-type="featured-content-section">

<div style="text-align:center;">

<h1 style="margin-bottom: 1px; margin-top: 50px;">Moisturize &amp; Nourish</h1>
