In this article, we will discuss how to create an HTML accordion without using JavaScript. An accordion is a graphical user interface that allows users to show or hide content by clicking on the accordion section headings. Traditionally, accordions are created using JavaScript, but in this article, we will explore how to create a simple accordion using only HTML and CSS. We will walk through the step-by-step process of creating an accordion, giving you a practical example to follow along with. By the end of this article, you will have a solid understanding of how to create an HTML accordion without relying on JavaScript.

What is an HTML Accordion?

An HTML accordion is a user interface element that allows users to toggle the display of content by clicking on section headings. When a section heading is clicked, the corresponding content is revealed, and other sections may collapse to make space for the newly opened section. Accordions are commonly used to organize and display large amounts of content in an easily navigable format.

To create an HTML accordion without using JavaScript, we will rely on the power of HTML and CSS to achieve the desired functionality. This approach has the advantage of reducing the reliance on JavaScript, which can improve the overall performance of a web page. Additionally, it provides an opportunity to learn how to create interactive user interfaces using basic web technologies.

How to Create an HTML Accordion Without Using JavaScript?

The first step in creating an HTML accordion without using JavaScript is to structure the HTML markup for the accordion. This involves creating a series of section headings and corresponding content sections, which will be collapsible and expandable. Each section heading will act as a toggle that controls the display of its associated content. Here’s a simple example of how the HTML markup might look for a basic accordion:

HTML

<details class="accordion-item">
  <summary class="accordion-title">Section 1 Title</summary>
  <div class="accordion-content">
    <p>Content for Section 1...</p>
  </div>
</details>

<details class="accordion-item">
  <summary class="accordion-title">Section 2 Title</summary>
  <div class="accordion-content">
    <p>Content for Section 2...</p>
  </div>
</details>

<details class="accordion-item">
  <summary class="accordion-title">Section 3 Title</summary>
  <div class="accordion-content">
    <p>Content for Section 3...</p>
  </div>
</details>

In this example, we have created a simple accordion with three sections. Each section consists of a button element acting as the section title and a div containing the section content.

The next step is to use CSS to style the accordion and hide the content sections by default. This involves setting up the necessary styles to create the accordion layout and control the visibility of the content sections. Here’s an example of how the CSS might look for styling the accordion:

CSS

.accordion-item:not([open]) .accordion-content {
  display: none;
}

.accordion-item[open] .accordion-content {
  display: block;
}

.accordion-title {
  cursor: pointer;
  padding: 10px;
  background-color: #eee;
  border: none;
  outline: none;
  width: 100%;
  text-align: left;
}

.accordion-content {
  padding: 10px;
  background-color: #f9f9f9;
  border-top: 1px solid #ddd;
}

In this CSS example, we use the display property to hide the content sections by default. We also set up styles for the section titles to make them appear clickable and provide a visual indicator of their toggled state. By using the :after pseudo-element, we can add a plus or minus symbol indicating whether the section is expanded or collapsed.

Finally, we can use CSS to add interactivity to the accordion by using the :active and :hover pseudo-classes. This allows us to control the visibility of the content sections when a section title is clicked or hovered over. Here’s an example of how the CSS might look for adding interactivity to the accordion:

CSS

.accordion-title::before {
  content: '+ ';
  font-weight: bold;
}

.accordion-item[open] .accordion-title::before {
  content: '- ';
}

In this CSS example, we use the adjacent sibling selector (+) to target the content section that follows a clicked section title. This allows us to display the content section when the corresponding section title is clicked. The .active class is used to maintain the visibility of the content section when it is toggled open.

By following these steps and incorporating the provided HTML and CSS examples, you can create a basic HTML accordion without using JavaScript. This approach provides a simple and lightweight solution for creating interactive user interfaces while reducing the reliance on JavaScript.
