> Is there a way to insert custom HTML by pointing to an independent HTML file that lives in a theme?

If you’re using the component with a custom theme, you could create a `.hbs` file in javascripts/discourse/components/ with the desired HTML, then instead of `custom-html` for the block use the name of a file (without the .hbs).

Edit: If anyone is wondering why we’d use `.hbs` instead of `.html` here, this method would create a custom [Ember.js](https://guides.emberjs.com/release/getting-started/) component that Right Sidebar Blocks can locate by name and use as one of the blocks. `.hbs` is a [handlebars](https://handlebarsjs.com/guide/) file. Handlebars is a “templating” language used by Ember.js that looks like HTML but lets you do things like inserting dynamic data, only showing an element based on a condition, or showing several copies of the same content filled with different data. If that sounds like fun, the [Beginner’s guide to developing Discourse Themes](https://meta.discourse.org/t/beginners-guide-to-developing-discourse-themes/93648/1#handlebars-templates-21) goes into how to use hadlebars and Ember components in Discourse Themes.
