HTML-
Here are the key concepts I can learn from this HTML code:
1. **HTML Structure**:
- `<!DOCTYPE html>`: Declares the document to be HTML5.
- `<html lang="en">`: Specifies the language of the document.
- `<head>`: Contains meta-information and external resources for the document.
- `<meta charset="UTF-8">`: Sets the character set for the document.
- `<meta http-equiv="X-UA-Compatible" content="IE=edge">`: Specifies the version of Internet Explorer to use.
- `<meta name="viewport" content="width=device-width, initial-scale=1.0">`: Sets the viewport properties for responsive design.
- `<title>`: Sets the title of the web page.
- `<link>`: Links external resources like CSS and favicon.
- `<body>`: Contains the visible content of the web page.
2. **Div Elements**:
- `<div class="app-main" id="parent">`: A container div for the entire application.
- `<div class="header">`: A div for the header section displaying the app name.
- `<div class="searchInputBox">`: A div containing an input box for the user to enter a city name.
- `<div class="weather-body" id="weather-body">`: A div where the weather information will be displayed.
3. **Input Element**:
- `<input type="text" name="" id="input-box" class="input-box" placeholder="Enter your city name">`: An input box where users can type the name of a city to get weather information.
4. **Script Tag**:
- `<script src="script.js"></script>`: Links an external JavaScript file for dynamic functionality.
5. **External Libraries**:
- **Font Awesome**:
- `<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.3/css/all.min.css">`: Imports Font Awesome icons for use in the application.
- **SweetAlert**:
- `<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script>`: Imports the SweetAlert library for displaying alert messages.
6. **Favicon**:
- `<link rel="shortcut icon" href="img/bg.jpg" type="image/x-icon">`: Sets a favicon for the web page, which is the small icon displayed next to the page's title in the browser tab.
7. **Responsive Design**:
- `<meta name="viewport" content="width=device-width, initial-scale=1.0">`: Ensures the web page is optimized for various devices by adjusting the viewport width and initial scale.
8. **Semantic HTML**:
- The use of `<div>` elements with class names like `app-main`, `header`, `searchInputBox`, and `weather-body` helps in organizing and structuring the content semantically, making the code more readable and maintainable.
In summary, this HTML code demonstrates the basic structure and layout of a Weather Finder web application. It incorporates input fields, containers, and external libraries to create a user-friendly interface for searching and displaying weather information.
CSS-
Here are some concepts and key takeaways I have learned:
1. **Font Import**:
- `@import url('https://fonts.googleapis.com/css2?family=Roboto&family=Ubuntu:wght@300&display=swap');`: Imports Google Fonts 'Roboto' and 'Ubuntu' with specific weights to be used in the web page.
2. **Universal Reset**:
- `*`: Targets all elements in the document.
- `margin: 0; padding: 0; box-sizing: border-box;`: Resets margins, paddings, and sets `box-sizing` to `border-box` to ensure consistent box sizing across elements.
3. **Background Styling**:
- `body`: Sets the background image, position, and size to create a visually appealing background for the webpage.
4. **Typography**:
- Styles for `.header h4` demonstrate font styling like color, weight, and size.
- Font stacks are used to provide fallback fonts in case the primary font fails to load.
5. **Layout and Box Model**:
- `.app-main`: Defines the styles for the main application container. It uses flexbox properties like `margin`, `padding`, `text-align`, `box-shadow`, and `border-radius` to create a centered, visually appealing container with a gradient background.
- `.app-main > *`: Targets all direct children of `.app-main` and applies margin-bottom to create space between them.
6. **Input Styling**:
- `.input-box`: Styles the input box with a specific background color, text color, font weight, and padding. It also applies a border-radius and removes default borders to give it a clean look.
7. **Weather Display**:
- `.weather-body`: Styles the container where the weather information will be displayed. It sets the text color, background color, padding, and border-radius. It also uses a gradient background for a visually appealing effect.
- `.temp`, `.weather`, `.min-max`, `.location-deatils`, `.weather-status`, `.sun-detail`, `.basic`: Styles specific elements inside the `.weather-body` container with appropriate font sizes, weights, and margins.
8. **Media Queries**:
- `@media screen and (max-width: 800px)`: Uses a media query to apply responsive styles for screens smaller than 800px.
- Adjusts `.app-main` width and body min-height to adapt to smaller screens.
9. **Gradient Backgrounds**:
- Uses both `-webkit-linear-gradient` and `linear-gradient` for cross-browser compatibility to create gradient backgrounds for elements.
10. **Visibility & Display**:
- `.weather-body`: Uses `display: none;` to initially hide the weather display until the user searches for a city.
- This can be toggled to `display: block;` or `display: flex;` in JavaScript to show the weather information dynamically.
11. **Color Schemes**:
- Uses consistent color schemes throughout the CSS to maintain a cohesive design.
- Color codes are used to define specific colors and gradients for elements.
12. **Font Weights and Sizes**:
- Defines various font weights and sizes for different elements to create a hierarchy and emphasis on important information.
Overall, this CSS code provides a comprehensive guide on how to style a Weather Finder web application, focusing on layout, typography, color schemes, and responsiveness. The use of Google Fonts, gradient backgrounds, and media queries showcases best practices for modern web design and development.
JS-
One key concept that can be learned from this code is the use of JavaScript to create interactive behavior on a webpage.
1. **Object Literal**:
- Creating an object (`weatherApi`) to store configuration details like API key and base URL. This promotes organization and makes it easier to manage configurations.
2. **Event Handling**:
- Adding an event listener to an input box to detect the 'Enter' keypress event. This allows the user to trigger an action (like fetching weather data) by pressing the 'Enter' key.
3. **Fetching Data from an API**:
- Using the `fetch` API to retrieve weather data based on the city name entered by the user.
- Handling the fetched data and converting it to JSON format.
4. **DOM Manipulation**:
- Updating the DOM dynamically with the fetched weather data using `innerHTML`.
- Changing the display style of an element to show or hide it.
5. **Conditional Statements**:
- Using `if-else` conditions to handle different cases based on the API response (e.g., handling empty input, invalid city, etc.).
6. **Date and Time Manipulation**:
- Creating a function to format and display the current date and time.
- Using `Date` objects to get the current date and time.
7. **Dynamic Styling**:
- Changing the background of the webpage dynamically based on the weather status fetched from the API.
8. **Functions and Reusability**:
- Defining utility functions like `changeBg`, `getIconClass`, `getTime`, `dateManage`, and `addZero` to perform specific tasks. This promotes code reusability and maintainability.
9. **Error Handling**:
- Using `swal` (SweetAlert) library to display user-friendly error messages for different scenarios.
10. **Input Reset**:
- Creating a function (`reset`) to clear the input box after fetching weather data.
11. **Modular Code**:
- Organizing code into separate functions to handle specific tasks, making it easier to read, debug, and maintain.
12. **Template Literals**:
- Utilizing template literals to create dynamic HTML content, making it easier to embed variables and expressions directly into strings.
Overall, this code provides a comprehensive example of how to fetch data from an API, handle user input, update the DOM dynamically, and create a user-friendly weather application. It demonstrates good practices in terms of code organization, error handling, and reusability.
