ในบทความนี้ คุณจะได้เรียนรู้วิธีสร้างหน้าเข้าสู่ระบบ แบบเคลื่อนไหวโดยใช้ HTML 5 และ CSS3 และจาวาสคริปต์เท่านั้น
ขั้นแรก
คุณสร้างไฟล์ index.html และเพิ่มโค้ด html และ javascript ต่อไปนี้
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" type="text/css" href="style.css">
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<title>Animated Panda Login Page</title>
</head>
<body>
<div class="panda">
<div class="ear"></div>
<div class="face">
<div class="eye-shade"></div>
<div class="eye-white">
<div class="eye-ball"></div>
</div>
<div class="eye-shade rgt"></div>
<div class="eye-white rgt">
<div class="eye-ball"></div>
</div>
<div class="nose"></div>
<div class="mouth"></div>
</div>
<div class="body"> </div>
<div class="foot">
<div class="finger"></div>
</div>
<div class="foot rgt">
<div class="finger"></div>
</div>
</div>
<form>
<div class="hand"></div>
<div class="hand rgt"></div>
<h1>Panda Login</h1>
<div class="form-group">
<input required="required" class="form-control"/>
<label class="form-label">Username </label>
</div>
<div class="form-group">
<input id="password" type="password" required="required" class="form-control"/>
<label class="form-label">Password</label>
<p class="alert">Invalid Credentials..!!</p>
<button class="btn">Login </button>
</div>
</form>
<script>
(function() {
$('#password').focusin(function(){
$('form').addClass('up')
});
$('#password').focusout(function(){
$('form').removeClass('up')
});
// validation
$('.btn').click(function(){
$('form').addClass('wrong-entry');
setTimeout(function(){
$('form').removeClass('wrong-entry');
},3000 );
});
});
// Panda Eye move
$(document).on( "mousemove", function( event ) {
var dw = $(document).width() / 15;
var dh = $(document).height() / 15;
var x = event.pageX/ dw;
var y = event.pageY/ dh;
$('.eye-ball').css({
width : x,
height : y
});
});
</script>
</body>
</html>
ขั้นที่ 2 สร้าง style.css และเพิ่มโค้ดต่อไปนี้:
@import url(https://fonts.googleapis.com/css?family=Dancing+Script|Roboto);
*, *:after, *:before {
box-sizing: border-box;
}

หลังจากเพิ่มโค้ด HTML และ CSS และจาวาสคริปต์ จากนั้นเปิด index.html ในเบราว์เซอร์ คุณจะเห็นผลลัพธ์ดังรูปด้านบน
