CSS
This HTML and CSS are for a very simple open/shut accordion style display.
/* Styles for open and shut or hide and display content in a pane with CSS only */
/* create a container */
#container div {
position: relative;
}
/* Make an input of type checkbox, and position it absolutely within the relative parent div */
input[type="checkbox"] {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
opacity: 0;
}
/* Make the cursor change when the label is moused over */
label {
cursor: pointer;
}
/* Make the label the full width of the page for usability */
label {
position: relative;
display: block;
}
/* Hide the checkbox */
label::before {
content: "";
position: absolute;
}
/* Set #pane to hidden by default / unclicked state */
#pane {
max-height: 0;
overflow: hidden;
transition: min-height 0.4s ease;
}
/* Set checkbox to display content when clicked */
input[type="checkbox"]:checked ~ h2 ~ #pane {
max-height: max-content;
}
/* Optional */
#container h2 {
border-bottom: 1px solid black;
