In my content type I have a thumbnail where I put the link to the image I want to embed into a view.
For the fields I have Content: Title [hidden] Content: Thumbnail
In views for the Content: Thumbnail I check "ReWrite Results" and add
<div class="vid-thumb">
<img src="http://img.youtube.com/vi/{{ field_thumbnail }}/0.jpg">
</div>
<div class="vid-title">{{ title_1 }}</div>
This displays the YouTube thumbnail in my view. The problem I am having is trying to make it so the user can click on the thumbnail to get to the content instead of having to click on the title which I display below.
I know twig can be used in the "Rewrite Results" but I wasn't sure what to call in there to add it to an href tag
<a href="{{ ???.??? }}"><img src="blah"></a>
