UPDATE @petermeissner

if you want to add a tittle and a body, you can use content: attr(data-title);

figure{
    width:400px;
    height:220px;
    border-radius:4px;
    border:2px solid #ccc;
    position:relative;
    padding:48px 10px 10px
}

figure:before {
    content: attr(data-title);
    position: absolute;
    top: 0px;
    left: 0;
    width: 100%;
    height: 40px;
    line-height: 40px;
    text-indent: 10px;
    border-bottom: 2px solid #ccc;
}

<figure data-title="Butter Cookies!">
  <figcaption>
    Homemade vanilla Danish butter cookies are the perfect cookie to share!         <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/figure">find out more about this Figure</a>
