How to create an FAQ section of a website using JavaScript?
In this article, we will be creating a FAQ (Frequently asked questions) accordion using JavaScript. The accordion is used to display the questions and will open up on clicking to display the answers. We can see the FAQ section on every website where all the top questions are covered. Today we will learn how to make these FAQ sections.
Steps for creating the Accordion
Step I −Firstly, we will be creating a nested HTML div tag that will hold all questions and answers. These div tags will depend upon the number of QnA to be displayed.
Step II − We will use CSS for providing a better user interface. Commonly used properties are font size, margin, padding, color, etc.
Step III − We will also be required to add a JavaScript function that will render the answers and display them on clicking. The answer will be displayed by clicking on the question.
Example
In the below example, we have added some questions and answers to them. These questions are displayed normally but the answers will only be displayed once the user clicks on them. We have placed an event listener to the button and as the user clicks on the link, it will open the div and display the answers.
