The advantages of using age calculator browser extensions are numerous:
Now, let's dive into the process of building and deploying an age calculator browser extension. We'll focus on creating a simple extension for Google Chrome using HTML, CSS, and JavaScript.
Create a new directory for your extension and set up the necessary files:
mkdir age-calculator-extension
cd age-calculator-extension
touch manifest.json
mkdir icons
touch popup.html popup.js style.css
The manifest file defines the structure and properties of your extension. Here's a basic example:
{
"manifest_version": 3,
"name": "Age Calculator",
"version": "1.0",
"description": "Calculate age based on birthdate.",
"action": {
"default_popup": "popup.html",
"default_icon": {
"16": "icons/icon16.png",
"48": "icons/icon48.png",
"128": "icons/icon128.png"
}
},
"permissions": [
"activeTab"
]
}
This file contains the user interface of your extension:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Age Calculator</title> <link rel="stylesheet" href="style.css"> </head> <body> <div class="container"> <h1>Age Calculator</h1> <label for="birthdate">Enter Birthdate:</label> <input type="date" id="birthdate"> <button id="calculate">Calculate Age</button> <div id="result"></div> </div> <script src="popup.js"></script> </body> </html>
This file contains the logic for calculating age based on the provided birthdate:
document.getElementById('calculate').addEventListener('click', function() { var birthdate = new Date(document.getElementById('birthdate').value); var today = new Date(); var age = today.getFullYear() - birthdate.getFullYear(); var monthDiff = today.getMonth() - birthdate.getMonth(); if (monthDiff < 0 || (monthDiff === 0 && today.getDate() < birthdate.getDate())) { age--; } document.getElementById('result').textContent = "Age: " + age; });
Style your extension's interface for better presentation:
body { font-family: Arial, sans-serif; background-color: #f4f4f4; } .container { max-width: 300px; margin: 0 auto; padding: 20px; background-color: #fff; border-radius: 5px; box-shadow: 0 2px 5px rgba(0, 0, 0, 0.1); } input[type="date"], button { display: block; width: 100%; margin-bottom: 10px; padding: 8px; } button { background-color: #007bff; color: #fff; border: none; border-radius: 3px; cursor: pointer; } button:hover { background-color: #0056b3; } #result { margin-top: 10px; font-weight: bold; }
Prepare icons for your extension in different sizes (16x16, 48x48, 128x128) and place them in the "icons" directory.
