Just as an FYI, in that page's source code, this appears to be the line used to create that non-button button. I don't think I've ever encountered class "btn-shape" before.
<div class="btn-shape"><a data-fancybox data-src="#form" class="btn btn--md btn--yellow btn--float mx-md--auto mb-md--20 b-r--50">GET INSTANT ACCESS</a></div>
The inventions in HTML coding are still very active indeed. [I'm sure someone will tell me, though, that btn-shape has been around forever after this.]
