This tutorial will mainly focus on how to use transitions in CSS to create a form input label wave.i used javascript to create the wave effect input label.when input is focused. Let's dive into the world of transition!
Today I have learned to wave the form input, in this I have done HTML CSS and JavaScript, also with the help of CSS, I have given the transition of the label in the input.
Here's My HTML code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="./style.css">
<title>Form Input Wave</title>
</head>
<body>
<div class="container">
<h1>PLease Login</h1>
<form>
<div class="form-control">
<input type="text" required>
<label>Email</label>
</div>
<div class="form-control">
<input type="password" required>
<label>Password</label>
</div>
<button class="btn">Login</button>
<p class="text">Don't have an account?</p>
<a href="#">Register</a>
</form>
</div>
<script src="./script.js"></script>
</body>
</html>
Here's My CSS code
@import url("https://fonts.googleapis.com/css?family=Ubuntu");
* {
box-sizing: border-box;
}
body {
background-color: steelblue;
color: #fff;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
font-family: "Ubuntu", sans-serif;
height: 100vh;
overflow: hidden;
margin: 0;
}
.container {
background-color: rgba(0, 0, 0, 0.4);
padding: 20px 40px;
border-radius: 5px;
}
.container h1 {
text-align: center;
margin-bottom: 30px;
}
.container a {
text-decoration: none;
color: lightblue;
}
.btn {
cursor: pointer;
display: inline-block;
width: 100%;
background: lightblue;
padding: 15px;
font-family: inherit;
font-size: 16px;
border: 0;
border-radius: 5px;
}
.btn:focus {
outline: 0;
}
.form-control {
position: relative;
margin: 20px 0 40px;
width: 300px;
}
.btn:hover {
color: #fff;
background-color: rgba(0, 0, 0, 0.4);
}
.btn:active {
transform: scale(0.98);
}
.text {
margin-top: 30px;
}
.form-control input {
background-color: transparent;
border: 0;
border-bottom: 2px #fff solid;
display: block;
width: 100%;
padding: 15px 0;
font-size: 18px;
color: #fff;
}
.form-control input:focus,
.form-control input:valid {
outline: 0;
border-bottom-color: lightblue;
}
.form-control label {
position: absolute;
top: 15px;
left: 0;
}
.form-control label span {
display: inline-block;
font-size: 18px;
min-width: 5px;
transition: 0.3s cubic-bezier(0.68, -0.55, 0.265, 1.55);
}
.form-control input:focus + label span,
.form-control input:valid + label span {
color: lightblue;
transform: translateY(-30px);
}
Here's My JAVASCRIPT code
const labels = document.querySelectorAll(".form-control label");
labels.forEach((label) => {
label.innerHTML = label.innerText
.split("")
.map(
(letter, idx) =>
`<span style="transition-delay:${idx * 50}ms">${letter}</span>`
)
.join("");
});
Here's output on Code pen lets see..

Nice and simple effect 👍
Here's a one liner because everyone's giving them out these days.
Hiya Ahtsham, me again, I spotted a bug 😩
The span labels sometimes get in the way on a mobile because they float above the input, a tap or click on the lettering then blocks the focus.
Never fear, here is one of several solutions
Now you can "click through" the spans as if they where ghosts 👻, spooky right?
