#html #css #javascript #tipcalculator

Introduction

Hello, fellow developers! I'm thrilled to introduce my latest project: a simple yet handy Tip Calculator. This project is a perfect opportunity to practice fundamental JavaScript concepts, such as handling user inputs, performing calculations, and dynamically updating the DOM. Whether you're new to JavaScript or looking for a small project to sharpen your skills, this Tip Calculator is a great choice.

Project Overview

The Tip Calculator is a web-based application that allows users to quickly calculate the total amount to pay, including the tip, based on the bill amount and tip percentage. The project demonstrates how to create an interactive user interface, manage calculations, and provide real-time feedback to the user.

Features

User-Friendly Interface: Simple and intuitive design for easy use.
Real-Time Calculation: Instantly calculates the total amount as you input the bill and tip percentage.
Responsive Design: The layout adjusts to different screen sizes, ensuring a seamless experience on both desktop and mobile devices.
Reset Functionality: Users can easily reset the input fields and start a new calculation.

Technologies Used

HTML: Structures the web page and input elements.
CSS: Styles the interface, ensuring a clean and responsive design.
JavaScript: Handles the calculation logic and updates the total amount in real-time.

Project Structure

Here's a quick look at the project structure:

Tip-Calculator/
├── index.html
├── styles.css
└── script.js

index.html: Contains the HTML structure for the Tip Calculator.
styles.css: Includes CSS styles to enhance the appearance of the calculator.
script.js: Manages the calculation logic and dynamic updates.

Installation

To get started with the project, follow these steps:

Clone the repository:

Enter the tip percentage to be added to the bill.
Click the "Calculate" button to see the total amount including the tip.
Reset the fields if you want to start a new calculation.

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">
        <p>Made with ❤️ by Abhishek Gurjar</p>
    </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);

Conclusion

Building this Tip Calculator was a fun and educational experience that reinforced my understanding of JavaScript, particularly in creating interactive web applications. I hope this project inspires you to experiment with JavaScript and build your own useful tools. Happy coding!
