<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Pastel Colored Notes</title>
    <link rel="stylesheet" href="styles.css"> <!-- External CSS file -->
</head>
<body>
    <div id="noteContainer" class="ns-note-container">
        <ul>
            <li><span class="ball pastel-yellow"></span> <span>→</span> Warning Message</li>
            <li><span class="ball pastel-green"></span> <span>→</span> Success Message</li>
            <li><span class="ball pastel-red"></span> <span>→</span> Error Message</li>
            <li><span class="ball pastel-blue"></span> <span>→</span> Information Message</li>
        </ul>
    </div>
</body>
</html>

2. CSS Styling

The styling ensures a clean, modern design with soft colors, rounded corners, and structured alignment.

body {
    font-family: Arial, sans-serif;
    background-color: #f8f8f8;
    padding: 20px;
}

.ns-note-container {
    background: #fff;
    padding: 15px;
    border-radius: 10px;
    box-shadow: 0px 4px 10px rgba(0, 0, 0, 0.1);
    max-width: 500px;
    margin: auto;
}

.ns-note-container ul {
    list-style: none;
    padding: 0;
}

.ns-note-container li {
    display: flex;
    align-items: center;
    gap: 10px;
    margin-bottom: 10px;
    font-size: 16px;
}

.ball {
    width: 16px;
    height: 16px;
    border-radius: 50%;
    display: inline-block;
}

.pastel-yellow { background-color: #FFF9C4; } /* Soft Yellow */
