This code creates an accordion in Vanilla JavaScript with plus and minus icons. The accordion expands or collapses its content when clicked. It helps organize and display content in a collapsible manner.
You can use this code on your website to create interactive FAQ sections or collapsible content panels. It enhances user experience by providing a neat and organized way to present information. Additionally, it improves readability by allowing users to focus on relevant content while hiding less important details.
How to Create Accordion In Vanilla Javascript With Plus Minus
1. First of all, load the Normalize CSS by adding the following CDN link into the head tag of your HTML document.
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/normalize/5.0.0/normalize.min.css">
2. Set up your HTML file. You’ll need a container for your accordion, along with individual sections for each accordion item. Inside your accordion container, add individual accordion items. Each item consists of a header and content section. Here’s an example of an accordion item:
<div class="app">
<div class="app__head">
<h1>Questions and answers about login</h1>
</div>
<div class="app__content">
<div class="accordion-container">
<div class="accordion ">
<header class="accordion__header">
<p>
<button>
<span class="accordion__title">Do I have to allow the use of cookies?</span>
<div class="accordion__icon">
<svg class="icon__plus" xmlns="http://www.w3.org/2000/svg" width="40" height="40">

3. You can style your accordion using CSS to achieve the desired look and feel. Here’s a basic example of CSS to get you started:
@import url("https://fonts.googleapis.com/css2?family=Mulish:wght@400;700&display=swap");
:root {
--clr-head: hsl(246, 35%, 11%);
--clr-body: hsl(248, 35%, 11%);
box-sizing: border-box;
}
*,
*::before,
*::after {
margin: 0;
padding: 0;
box-sizing: inherit;
}
html {
width: 100%;
height: 100%;
font-size: 62.5%;
}
body {
font-family: "Mulish", sans-serif;
width: 100%;
min-height: 720px;
font-size: 1.6rem;
color: var(--clr-body);
display: flex;
align-items: center;
justify-content: center;
background-color: #50155b;
}
.app {
max-width: 66em;
width: 100%;
background-color: white;
border-radius: 10px;
position: relative;
padding: 3em;
display: grid;
grid-template-columns: 0.8fr 1fr;
gap: 2rem;
}
.app__head {
margin-top: 2em;
}
.app__head h1 {
font-size: clamp(3rem, 5vw, 3.6rem);
font-weight: 700;
width: 80%;
line-height: 1.2;
}
.accordion {
margin-bottom: 0.5em;
max-width: 588px;
border-radius: 3px;
width: 100%;
border: 1px solid #e6e6e6;
cursor: pointer;
}
.accordion.is-open {
box-shadow: 0 18px 20px -10px rgba(80, 21, 91, 0.32);
border-radius: 3px;
}
.accordion__header button {
display: flex;
align-items: center;
justify-content: space-between;
width: 100%;
border: 0;
background-color: #fff;
padding: 2em;
text-align: left;
outline: none;
}
.accordion__title {
font-size: 1.8rem;
/* font-size: clamp(); */
font-weight: 400;
}
.accordion__icon {
cursor: pointer;
}
.accordion .accordions__icon > * {
width: 4rem;
}
.accordion .icon__plus {
display: block;
}
.icon__minus {
display: none;
}
.accordion.is-open .icon__minus {
display: block;
}
.accordion.is-open .icon__plus {
display: none;
}
.accordion__content {
height: 0;
overflow: hidden;
transition: height 0.3s ease-out;
}
.accordion__inner {
max-width: 80%;
width: 100%;
padding: 1em 1.5em;
}
.accordion__inner p {
font-size: 1.6rem;
line-height: 1.4;
margin-bottom: 1em;
color: var(--clr-body);
opacity: 0.7;
}
@media (max-width: 768px) {
.app {
max-width: 90%;
margin: 0 auto;
display: grid;
grid-template-columns: 1fr;
gap: 3rem;
}
.app__head h1 {
width: 90%;
}
.app::before {
display: none;
}
.app::after {
display: none;
}
}
4. Finally, add JavaScript to make your accordion interactive. This script will handle the opening and closing of accordion items when clicked.
// Design by https://uidesigndaily.com/posts/sketch-accordion-website-day-1175
const accordionContainer = document.querySelector(".accordion-container");
// select accordion header
accordionContainer.addEventListener("click", e => {
const accordionHeader = e.target.closest(".accordion__header");
if (accordionHeader) {
const accordion = accordionHeader.parentElement;
const accordionContent = accordionHeader.nextElementSibling;
const accordionInner = accordionContent.children[0];
let height;
if (accordion.classList.contains("is-open")) {
height = 0;
} else {
height = accordionInner.getBoundingClientRect().height;
}
accordion.classList.toggle("is-open");
accordionContent.style.height = `${height}px`;
}
});
