Adding a custom HTML block to a view I have a view in Drupal 8 that looks as follows (see screenshot). To make the long story short, I need to make this view output a fixed HTML block (piece of code, not Drupal Block) and not pull any dynamic data from the respective content type.

What is the most efficient way of doing this?
In your screen shot, there is HEADER and FOOTER section. Click add in one of them and add a Global: Text Area, and put your HTML there, for text filter use FULL HTML.
