Recap of Session
#132:

Accordion folding

  1. Inspect repository

  2. (within project directory), type into terminal:

quarto add royfrancis/quarto-accordion

YAML:

---
title: Accordion
accordion:
  - accordion-1:
    - header: Click here to view contents
      body: This is the body content
      collapsed: true
      id: custom-item-1
---

{{< accordion accordion-1 >}}
1
Use this label (here “accordion-1”) to execute content within body of document (e.g., on line #11)

in–line:

{{< accordion 
  header="Click here to view contents" 
  body="This is the body content" 
  collapsed=true 
  id="custom-item-1" >}}
1
id’s are auto–generated but can also be manually specified if desired. Seemingly most useful for direct links
This is the body content

Help pages have a section on css styling – AI can help craft styling specifications

.quarto-accordion .accordion-item {
  background-color: white;          
  border-color: black;
  margin-bottom: 8px;
  border-radius: 6px;
  overflow: hidden;
}

.quarto-accordion .accordion-button {
  background-color: #0a58ca;
  color: white;
  font-weight: 500;
}

.quarto-accordion .accordion-button:not(.collapsed) {
  background-color: #ade8f4;           
  color: #000000;
  box-shadow: none;
}

.quarto-accordion .accordion-body {
  background-color: #f8f9fa;
