Link to open accordion

Recommended Posts

I followed the tutorial to create an accordion. Now, I would like to link to individual headers in that accordion and have them load opened. How can I edit the code to do this?


Here is what I'm using:

<style type="text/css">.accordion {
  background: none;
  color: #3d8bb1;
  cursor: pointer;
  padding: 18px;
  width: 100%;
  border: none;
  text-align: left;
  outline: none;
  font-size: 18px;
  font-weight: bold;
  transition: 0.4s;

.active, .accordion:hover {
  background: none;
  color: #2e6885;

.accordion:after {
  content: '\002B';
  color: #2e6885;
  font-weight: bold;
  float: right;
  margin-left: 5px;

.active:after {
  content: "\2212";

.panel {
  padding: 0 18px;
  background-color: white;
  max-height: 0;
  overflow: hidden;
  transition: max-height 0.2s ease-out;
<button class="accordion">TITLE</button>
<div class="panel">
<p> CONTENT</p>

<button class="accordion">TITLE</button>
<div class="panel">

var acc = document.getElementsByClassName("accordion");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].addEventListener("click", function() {
    var panel = this.nextElementSibling;
    if (panel.style.maxHeight){
      panel.style.maxHeight = null;
    } else {
      panel.style.maxHeight = panel.scrollHeight + "px";
