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 🚀.
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">

Step 4: CSS Code
* {
margin: 0;
padding: 0;
box-sizing: border-box;
font-family: "Poppins", sans-serif;
}
body {
display: flex;
justify-content: center;
align-items: center;
background-color: #4e4cff;
}
.calculator {
margin-top: 7rem;
display: flex;
flex-direction: column;
background-color: white;
border-radius: 15px;
height: 30rem;
width: 20rem;
padding: 20px 30px;
}
#totalBill {
margin: 10px 0;
height: 38px;
border: none;
background: #f1f1f1;
padding: 0 10px;
border-radius: 5px;
}
#totalBill:focus {
outline: 2px solid #4b49f1;
}
input[type='range'] {
accent-color: #4b49f1;
margin: 10px 0;
}
.result {
width: 100%;
min-height: 100px;
margin-top: 20px;
padding: 20px;
background-color: #4b49f1;
border-radius: 15px;
font-size: 1.2rem;
color: white;
}
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 = `
<h5 style="margin: 8px 0;display: flex; justify-content:space-between;">
<span>Tip</span>
<span style="font-size:1.2rem;">${tip.toFixed(2)}</span>
</h5>
<h5 style="margin: 8px 0;display: flex; justify-content:space-between;">
<span>Total</span>
<span style="font-size:1.2rem;">${totalBill.toFixed(2)}</span>
</h5>
<h5 style="margin: 8px 0;display: flex; justify-content:space-between;">
<span>Each Person Pay</span>
<span style="font-size:1.2rem;">${perPersonPay.toFixed(2)}</span>
</h5>
