Code Explanation
HTML
The index.html file provides the basic structure of the Tip Calculator, including the input fields for the bill amount and tip percentage, as well as the button to trigger the calculation. Here’s a snippet:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Tip Calculator</title>
<link rel="stylesheet" href="./style.css">
<script src="./script.js" defer></script>
</head>
<body>
<div class="container">
<h1>Tip Calculator</h1>
<p>Enter the bill amount and tip percentage to calculate the total amount</p>
<label for="bill">Bill amount:</label>
<input type="number" id="bill">
<br>
<label for="tip">Tip percentage:</label>
<input type="number" id="tip">
<br>
<button id="calculate">Calculate</button>
<br>
<label for="total">Total Amount:</label>
<span id="total"></span>
</div>
<div class="footer">

</div>
</body>
</html>
CSS
The styles.css file styles the Tip Calculator, providing a clean and responsive layout. Here are some key styles:
* {
box-sizing: border-box;
}
body {
color: white;
background-color: white;
font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
}
.container {
background-color: rgb(0, 0, 0);
max-width: 600px;
margin: 100px auto;
padding: 20px;
box-shadow: inset;
border-radius: 10px;
}
h1 {
text-align: center;
}
input {
padding: 10px;
border: 1px solid #ccc;
border-radius: 4px;
margin: 10px 0;
width: 100%;
}
button {
background-color: green;
color: white;
padding: 10px;
border: none;
cursor: pointer;
margin: 10px 0;
text-transform: uppercase;
transition: background-color 0.2s ease;
}
button:hover {
background-color: #45a049;
}
#total {
font-size: 24px;
font-weight: bold;
margin-top: 10px;
}
.footer {
margin: 70px;
text-align: center;
color: black;
}
JavaScript
The script.js file handles the calculation logic, updating the total amount based on user inputs. Here’s a snippet:
const btn = document.getElementById("calculate");
const inputBill = document.getElementById("bill");
const inputTip = document.getElementById("tip");
const totalSpan = document.getElementById("total");
function calculateTotal() {
const billValue = parseFloat(inputBill.value);
const tipValue = parseFloat(inputTip.value);
const totalValue = billValue * (1 + tipValue / 100);
totalSpan.innerText = totalValue.toFixed(2);
}
btn.addEventListener("click", calculateTotal);
