Tip Calculator

Hello Guys! In this blog, I'm going to explain to you how to make a Tip Calculator using HTML, CSS, and JavaScript. You can use this project and upgrade it as a huge app by adding more calculation functionalities to it. This will be a step-by-step guide. Let's get started πŸš€.

Let's go step by step:

Step 1: IMPORT font awesome CDN

Now let's import the font awesome CDN in our HTML head tag. fontawesome is a library that is used for icons in a website.

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
integrity="sha512-+4zCK9k+qNFUR5X+cKL9EIR+ZOhtIloNl9GIKS57V1MyNsYpYcUrUeQc9vNfzsWfV28IaLL3i96P9sdNyeRssA=="
crossorigin="anonymous" />

Step 2: IMPORT fonts CDN from google fonts

Now let's import the fonts using Google Fonts API. Below is the code for Poppins Font. Paste the below code in head tag.

<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link href="https://fonts.googleapis.com/css2?family=Poppins&display=swap" rel="stylesheet">


Step 3: HTML Code


<html lang="en">

    <head>
        <!-- Required meta tags -->
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
    
        <!-- Font Awesome Icons  -->
        <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.1/css/all.min.css"
            integrity="sha512-+4zCK9k+qNFUR5X+cKL9EIR+ZOhtIloNl9GIKS57V1MyNsYpYcUrUeQc9vNfzsWfV28IaLL3i96P9sdNyeRssA=="
            crossorigin="anonymous" />
    
        <!-- Google Fonts  -->
        <link rel="preconnect" href="https://fonts.googleapis.com">
        <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
        <link href="https://fonts.googleapis.com/css2?family=Poppins&display=swap" rel="stylesheet">

            </label>
            <input type="range" oninput="calculateTip()" onchange="calculateTip()" id="tipPercentage">
            <label for="numOfPerson" style="display: flex; justify-content:space-between;">

                </h5>
            </div>

Step 5: JavaScript Code

let result = document.getElementById("result");

const calculateTip = () => {
    let bill = Number(document.getElementById("totalBill").value);
    let numOfPerson = Number(document.getElementById("numOfPerson").value);
    let tipPercentage = Number(document.getElementById("tipPercentage").value);

    let tip = bill * (tipPercentage / 100);
    let totalBill = bill + tip;
    let perPersonPay = (totalBill / numOfPerson);

    document.getElementById("tipPercentageText").innerHTML = `${tipPercentage}%`;
    document.getElementById("numOfPersonText").innerHTML = `${numOfPerson}`;

    result.innerHTML = `
