HTML is an example of declarative programming because it … Examples of these are HTML, SQL, F#, Prolog, and Lisp. I've also added a better method for example 1 suggested by deno. Procedural knowledge (also known as knowing-how, and sometimes referred to as practical knowledge, imperative knowledge, or performative knowledge) is the knowledge exercised in the performance of some task.

Imperative vs. Declarative Processes Models. Although Wikipedia contrasts this with the notion of declarative (functional, logic-oriented) vs. imperative (procedural, object-oriented) languages, I think this fits quite nicely, as the concepts of functional or logic-oriented programs are based on descriptions (of functions, facts, and rules), whereas procedural or object-oriented programs are made up of a sequence of commands.
