I'm trying to add the accordion in my page. But when I click the button it's not toggling.
Here is my Html
var acc = document.getElementsByClassName("accordion");
var i;
for (i = 0; i < acc.length; i ) {
acc[i].addEventListener("click", function() {
this.classList.toggle("active");
var panel = this.nextElementSibling;
if (panel.style.maxHeight) {
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight "px";
}
});
}
.blks {
.accordion {
background-color: #eee;
color: #444;
cursor: pointer;
padding: 18px;
width: 100%;
border: none;
text-align: left;
outline: none;
font-size: 15px;
transition: 0.4s;
&:after {
content: '\002B';
color: #777;
font-weight: bold;
float: right;
margin-left: 5px;
}
&:hover {
background-color: #ccc;
}
}
.active {
background-color: #ccc;
&:after {
content: "\2212";
}
}
.panel {
padding: 0 18px;
background-color: white;
max-height: 0;
overflow: hidden;
transition: max-height 0.2s ease-out;
}
}

CodePudding user response:
Your stylesheet is sass/scss and needs to be compiled or translated to plain CSS (which is the answer to your question)
Also I suggest you delegate
document.querySelector(".blks").addEventListener("click", function(e) {
const tgt = e.target;
if (!tgt.matches(".accordion")) return; // not a button
tgt.classList.toggle("active");
var panel = tgt.nextElementSibling;
if (panel.style.maxHeight) {
panel.style.maxHeight = null;
} else {
panel.style.maxHeight = panel.scrollHeight "px";
}
});
.blks .accordion {
background-color: #eee;
color: #444;
cursor: pointer;
padding: 18px;
width: 100%;
border: none;
text-align: left;
outline: none;
font-size: 15px;
transition: 0.4s;
}
.blks .accordion:after {
content: '\002B';
color: #777;
font-weight: bold;
float: right;
margin-left: 5px;
}
.blks .accordion:hover {
background-color: #ccc;
}
.blks .active {
