Whether you are just starting to learn about web development or looking to enhance your current skills, understanding the basics is essential. In this blog post, we will cover everything you need to know about web development, from the fundamentals to the latest trends in the industry.
Front-end Development
Front-end development, also known as client-side development, is the process of creating the user interface of a website or web application. It involves using programming languages such as HTML, CSS, and JavaScript to design the look and feel of a website and make it interactive.
HTML
HTML (HyperText Markup Language) is the backbone of every website. It is used to structure the content of a webpage and define its elements, such as headings, paragraphs, images, and links. The latest version of HTML, HTML5, has improved the semantic structure of web pages, making them more accessible and easier to code.
HTML uses tags to structure content and tell the browser how to display it. Tags are written between angle brackets , with opening and closing tags surrounding the content they apply to. For example, the tag denotes a main heading, while the tag denotes a paragraph.
CSS
CSS (Cascading Style Sheets) is used to style the elements on a webpage, making it visually appealing. It allows developers to control the colors, fonts, layouts, and other aspects of the design. By separating the presentation from the content, CSS makes it easier to make changes to a website’s appearance without affecting its underlying structure.
CSS works by applying rules to HTML elements. These rules can be written within the tags in the head section of an HTML document, or in a separate CSS file and linked to the HTML document. This makes it possible to style multiple web pages with the same CSS file, saving time and effort.
JavaScript
JavaScript is a programming language that adds interactivity to a website. It allows developers to create dynamic and responsive elements, such as animations, games, and form validations. JavaScript code can be inserted into an HTML document using the tags, or it can be stored in a separate file and linked to the HTML document.
JavaScript has become an essential part of web development, with its use expanding beyond just front-end development. It is now used in back-end development, mobile app development, and even game development.
Back-end Development
Back-end development, also known as server-side development, is the process of building the behind-the-scenes functionality of a website or web application. It involves creating and managing servers, databases, and applications that power a website’s front-end.
