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);
