I came across a tutorial on w3school (https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_collapsible_symbol), which demonstrates collapsible content hidden by default. The code snippet from the link is provided below. Can someone assist me in changing the default behavior from collapsible content hidden to content visible (shown) by default? Thank you!
var coll = document.getElementsByClassName("collapsible");
var i;
for (i = 0; i < coll.length; i++) {
coll[i].addEventListener("click", function() {
this.classList.toggle("active");
var content = this.nextElementSibling;
if (content.style.maxHeight){
content.style.maxHeight = null;
} else {
content.style.maxHeight = content.scrollHeight + "px";
}
});
}/* Styling for the button used to toggle collapsible content */
.collapsible {
background-color: #777;
color: white;
cursor: pointer;
padding: 18px;
width: 100%;
border: none;
text-align: left;
outline: none;
font-size: 15px;
}
/* Adjusting colors and styles when the button is clicked or hovered over */
.active, .collapsible:hover {
background-color: #555;
}
.collapsible:after {
content: '\002B'; /* Unicode character for a plus sign (+) */
color: white;
font-weight: bold;
float: right;
margin-left: 5px;
}
.active:after {
content: "\2212"; /* Unicode character for a minus sign (-) */
}
.content {
padding: 0 18px;
max-height: 0;
overflow: hidden;
transition: max-height 0.2s ease-out;
background-color: #f1f1f1;
