On whichever page you want to display your product / project portfolio, invoke the custom element like so:
<article id="project-neighbourhood">
<div class="row">
<div class="col-12 hero">
<img src="path-to-hero-image">
</div>
</div>
<tool-bar link2-share="http://www.mywebsite.com/neighbourhood" link2-fork="https://github.com/myusername/neighbourhood" modal-id="project-neighbourhood-map" title="project-neighbourhood-map">
<div class="col-12">
<p> a single-page application featuring a map of my neighborhood or a neighborhood I would like to visit. I will then add additional functionality to this application, including: map markers to identify popular locations or places you’d like to visit, a search function to easily discover these locations, and a listview to support simple browsing of all locations. I will then research and implement third-party APIs that provide additional information about each of these locations (such as Street View images, Wikipedia articles, Yelp reviews, etc).</p>
</div>
</tool-bar>
</article>
and you get this as preview
