Abstract title does not show up in quarto pdf document

Question

Consider the following quarto document:

---
title: "Untitled"
format: pdf
abstract: |
  This is the abstract.
abstract-title: My abstract
---

Something.

The PDF output does not contain the abstract title. How can we fix that?

Answer 1

Firstly, you need to pass the option abstract to the documentclass scrartcl to show the abstract title.

---
title: "Untitled"
format: pdf
classoption: abstract
keep-tex: true
abstract: |
  This is the abstract
---

Something.

Now following the above, will show the abstract title, titled as Abstract by default. If you want a different abstract title, modify the \abstractname with \renewcommand{\abstractname}{<custom-abstract-title>}.

title: "Untitled"
format: pdf
classoption: abstract
abstract: |
  This is the abstract
include-in-header: 
  text:
    \renewcommand{\abstractname}{My abstract}
---

Something.
