Weather app Free Source Code

To write the code for a weather web app in HTML, CSS, and JS, you will need to have a basic understanding of how these languages work.

HTML is used to structure the content of your web page. It consists of elements, such as <h1>, <p>, and <img>, which are used to represent different types of content, such as headings, paragraphs, and images.

CSS is used to style the content of your web page. It allows you to control things like the font, color, and layout of your elements.

JS is used to add interactivity to your web page. It allows you to respond to user events, such as clicks and keystrokes, and to manipulate the DOM (Document Object Model), which is the representation of your web page in memory.

Here is a brief overview of the steps involved in writing the code for a weather web app:

Create an HTML file. This file will contain the basic structure of your web page, including the elements that you need to display the weather data.

Add CSS to your HTML file. This will allow you to style your web page and make it look more visually appealing.

Add JS to your HTML file. This will allow you to fetch the weather data from an API and display it on your web page.

Here is a more detailed explanation of each step:

Creating an HTML file

To create an HTML file, you can use a simple text editor, such as Notepad or TextEdit. Once you have created the file, save it with a .html extension.

Here is a simple example of an HTML file for a weather web app:

HTML:

<!DOCTYPE html>
<html lang="en">
<head>
<title>Weather App</title>
</head>
<body>
<h1>Weather App</h1>
<div id="weather-card"></div>
</body>
</html>

This HTML file creates a basic structure for your web page with a heading and a div element with the ID weather-card. This is where you will display the weather data.

Adding CSS to your HTML file

To add CSS to your HTML file, you can either inline the CSS in the style attribute of your elements or you can create a separate CSS file and link to it in the <head> section of your HTML file.

Here is a simple example of CSS that you could use to style your weather web app:

css:

body {
font-family: sans-serif;
}
#weather-card {
margin: 0 auto;
width: 500px;
padding: 10px;
border: 1px solid #ccc;
}

This CSS will center the weather card on the page and style the border.

Adding JS to your HTML file

To add JS to your HTML file, you can either inline the JS in the script tag in the <head> section of your HTML file or you can create a separate JS file and link to it in the <body> section of your HTML file.

Here is a simple example of JS that you could use to fetch the weather data from an API and display it in the weather card:

const weatherCard = document.querySelector("#weather-card");

// Fetch the weather data from an API

fetch("https://api.openweathermap.org/data/2.5/weather?q=London&appid=YOUR_API_KEY")

.then(response => response.json())

.then(data => {

// Update the weather card with the weather data

weatherCard.innerHTML = `

<p>${Math.round(data.main.temp - 273.15)}°C</p>

<p>${data.weather[0].description}</p>

});

This JS will fetch the weather data for London from the OpenWeatherMap API and display it in the weather card. You can change the city by changing the q parameter in the API call.

This is just a basic example of how to write the code for a weather web app in HTML, CSS, and JS. You can customize it to add more features, such as a forecast or support for multiple cities.
