JQuery, Javascript, AJAX, HTML, Bootstrap, CSS-web design and development tools

Example

Use JavaScript to dynamically add items to a shopping cart without refreshing the page.

Scenario

In e-commerce websites, JavaScript is often used to update the cart when users select a product. With event listeners and DOM manipulation, the shopping cart can be updated in real-time.

Example

Using jQuery's `$('#element').hide()` to hide an HTML element with a single line of code.

Scenario

On a product page, a user clicks a button, and jQuery hides or shows additional information about the product without writing complex JavaScript.

Example

AJAX call using `$.ajax({url: '/get-data', success: function(data){ console.log(data); }})`.

Scenario

In a weather application, AJAX is used to fetch real-time weather data from an external API without refreshing the page, ensuring a seamless user experience.

Example

<h1>Welcome to My Website</h1><p>This is a paragraph of content.</p>

Scenario

When building a blog, HTML is used to define the structure of the webpage, with headings, paragraphs, images, and links to guide user navigation.

Example

Using Bootstrap’s grid system: `<div class='col-md-6'>Content</div>`.

Scenario

For a portfolio website, Bootstrap helps ensure that the website layout adjusts based on the screen size, making it mobile-friendly and consistent across devices.

Example

Defining a website's background color and text styles: `body { background-color: #f4f4f4; font-family: Arial, sans-serif; }`.

Scenario

For a landing page, CSS ensures that the background is a soft gray and the text is styled with a consistent font, improving the aesthetics and readability.
