3. Use JavaScript to control the div Hiding and showing elements
If you want to control the hiding and showing of div elements when the user clicks a button, you can use JavaScript to achieve this.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>显示/隐藏div元素</title>
<style>
#myDiv {
width: 200px;
height: 200px;
background-color: #ccc;
display: block;
}
</style>
</head>
<body>
<button onclick="toggleDiv()">显示/隐藏div元素</button>
<div id="myDiv"></div>
<script>
function toggleDiv() {
var div = document.getElementById("myDiv");
if (div.style.display === "none") {
div.style.display = "block";
} else {
div.style.display = "none";
}
}
</script>
</body>
</html>
In the example, when the user clicks the button, the div element with the ID myDiv is obtained through JavaScript, and it is determined whether the display style attribute of the element is none. If so, it is set to block. Otherwise set it to none. This implements the hiding and display of div elements.
