I'm using Drupal 8 and building a view. I have a field, which happens to be a title field, and I have set it to link to content. I would like to know how I can simply add a btn class to the anchor tag. Right now the output looks like this:
<a href="/node/{id}" hreflang="en">... custom text ...</a> I know I can use the Rewrite Results view feature to accomplish this, however, I need more power than that because I am building a theme for a client. The theme needs to be more generic, so I need to be able to accomplish this in a template. Is there template suggestion/hook that would allow me to override this in a template such as .../templates/views-view-field--link.html.twig? Or is there a theme function that I could use to override the markup by adding the class I would like?
I've considered using the views-view-field.html.twig template and overriding the node_view type to accomplish this, but I'm not sure how to do that whilst keeping the custom text a user could be using because it's really hard to debug the field options.
Edit
###Edit II forgot to mention, this needs to rely on Drupal core. I can't expect the user to install any additional modules for it to work.
