Accordion code not working

Hi Arnel,

Here’s the CSS code I’ve added to Custom Code section:

.boldgrid-css{ background: white; }
/* Style the buttons that are used to open and close the accordion panel */
button.accordion {
background-color: #eee;
color: #444;
cursor: pointer;
padding: 18px;
width: 100%;
text-align: left;
border: none;
outline: none;
transition: 0.4s;
}

/* Add a background color to the button if it is clicked on (add the .active class with JS), and when you move the mouse over it (hover) */
button.accordion.active, button.accordion:hover {
background-color: #ddd;
}

/* Style the accordion panel. Note: hidden by default */
div.panel {
padding: 0 18px;
background-color: white;
display: none;
}
button.accordion:after {
content: ‘2795’; /* Unicode character for “plus” sign (+) */
font-size: 13px;
color: #777;
float: right;
margin-left: 5px;
}

button.accordion.active:after {
content: “2796”; /* Unicode character for “minus” sign (-) */
}
div.panel {
padding: 0 18px;
background-color: white;
max-height: 0;
overflow: hidden;
transition: max-height 0.2s ease-out;
}

I’ve also added JS:

// jQuery(‘body’);
var acc = document.getElementsByClassName(“accordion”);
var i;

for (i = 0; i < acc.length; i++) {
acc[i].onclick = function(){
/* Toggle between adding and removing the “active” class,
to highlight the button that controls the panel */
this.classList.toggle(“active”);

/* Toggle between hiding and showing the active panel */
var panel = this.nextElementSibling;
if (panel.style.display === “block”) {
panel.style.display = “none”;
} else {
panel.style.display = “block”;
}
}
}
//open and close accordion
var acc = document.getElementsByClassName(“accordion”);
var i;

for (i = 0; i < acc.length; i++) {
acc[i].onclick = function() {
this.classList.toggle(“active”);
var panel = this.nextElementSibling;
if (panel.style.maxHeight){
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight + “px”;
}
}
}

And HTML on the page:
<button class=”accordion”>Section 1</button>
<div class=”panel”>
<p>”section text”</p>
</div>

Here’s where I got the code from:
