    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Welcome Onboard</title>
    <link rel="stylesheet" href="style.css">

<body>

    <div class="container">

        <div class="welcome-card">
            <img src="your-logo.png" alt="Logo" class="logo">

            <h1>Welcome Onboard!</h1>
            <p class="subtitle">

                Your journey begins now—let’s get started!

            <a href="#" class="btn">Get Started</a>
        </div>

    </div>

</body>
</html>

🎨 style.css

    padding: 30px;
    border-radius: 12px;
    box-shadow: 0 10px 35px rgba(0, 0, 0, 0.2);

}

/* Headings */
h1 {

    padding: 12px 25px;
    border-radius: 6px;

}

/* Animation */
@keyframes fadeIn {
    from { opacity: 0; transform: translateY(25px); }
    to { opacity: 1; transform: translateY(0); }
}

3. Optional: Add JavaScript Animation

Create script.js:

document.querySelector(".btn").addEventListener("click", function () {
    alert("Welcome onboard! Let's begin your journey.");
});

Include it in your HTML:

<script src="script.js"></script>

4. How It Works (Detailed Explanation)

HTML

The <div class="welcome-card"> forms the main card
<h1> is your welcome message
<p> adds a friendly introduction
<a class="btn"> creates a CTA button
<img class="logo"> displays logo or icon

CSS

linear-gradient() creates a smooth colorful background
box-shadow makes the card appear elevated
border-radius softens the edges
fadeIn animation makes the card appear smoothly

Responsive Design

max-width: 500px keeps card centered on large screens
width: 90% ensures mobile compatibility

5. How to Add Your Logo or Image

Replace:

<img src="your-logo.png" alt="Logo" class="logo">

Use:

A local file (logo.png)
Or an online image URL

Example:

<img src="https://example.com/logo.png" class="logo">

6. Customization Options

In CSS:

background: linear-gradient(135deg, #FF7A00, #FFB347);
