Understanding Web Development What is Web Development?Web development involves the processes of designing, creating, and managing websites. It is versatile in that it incorporates graphic design of websites, development of contents for websites, client-side and server-side scripting, and configuration of security measures of an organization’s network. Web development can be divided into three main categories: Front-End Development: This represents all those entities that are directly accessible to the users. It entails the appearance and structure of a website as well as the superior functionality of the site. HTML, CSS, and JAVASCRIPT are some of the technologies that are used in development. There are three major areas in the sphere of web development: front-end, back-end, and full-stack. Front-End Development: Keeps some distance from the content and its content relies heavily on looks and usability. They can be HTML, CSS, JS, and various frameworks such as React, Angular, or Vue. Js.Back-End Development: It is centered on server logic, and databases, along with a server environment and settings. Server-side languages can be Node. Js, Python, PHP, and frameworks can be Express. Js, Django, and Ruby on Rails while databases are MySQL, PostgreSQL, and MongoDB.Full-Stack Development: It involves both front-end and back-end professionals with computer programming languages. Both areas are known by full-stack developers, which is why they can perform operations both at the client and server levels. The exact job description of a web developer varies depending on the specifics of the position, but in general, the following is expected: Front-End Developer: Concerned with the actual presentation of the application’s front-end and is the last part of the design to be developed. They collaborate with designers to turn mockups and wireframes into fully functional sites, and also, guarantee that the created website is accessible.Back-End Developer: Back-End Developer: He is the server and application guy. He works on the logic and the database.Full-Stack Developer: Both involve working on the front-end and back-end but are more involved with the back-end. With the skill set of a good programmer at their beck and call, it enables them to take a project right from the very initial stage to the end, knowing that half of the work is always on the client-side and the other half on the server side. Getting Started with HTML Introduction to HTMLHTML is the standard markup language used to develop web pages; it stands for HyperText Markup Language. It forms the skeleton in the creation of a web page and is applied to classify parts like headlines, texts, links, images, and other media. HTML Document Structure and Organization of Basic ElementsHTML tags are nested and work as organizing blocks of an HTML document. The basic structure includes: Introduction to CSS What is CSS?CSS (Cascading Style Sheets) is a style sheet language used to describe the format of any web document written in HTML. CSS stands for Cascading Style Sheets It handles everything that has to do with the placement of objects on a website, colors of objects on the site, fonts, and indeed the general outlook of the site. This article explains how CSS works with HTML as a complementary link rather than a subordinative tool to HTML, contrary to many people’s mentality. One of the ways CSS works is that it selects HTML elements and gives them styles. Inline CSS: Using the style attribute directly on an HTML element.Internal CSS: Using the style element inside the head section of an HTML document.External CSS: Linking to an external CSS file using the link element. JavaScript for Beginners JavaScript: What is it? Why Does It Matter?JavaScript is a high-level interpreted computer language that makes web pages dynamic. One of the critical aspects of the web development process, that it makes it possible to develop dynamic interfaces. JavaScript itself is a client-side language for scripting, but with technologies like Node.js, it may also be put into action on the server side. Syntax of JavaScript and some of the most fundamental features.Variables: Appears to be utilized for storing the data value.Functions: A block of code designed to perform some particular task.Events: Code structures that listen for and handle user interactions. Adding Interactivity to Your Web PagesYou can add interactivity to your web pages by manipulating the DOM (Document Object Model) using JavaScript. Here is an example of how you would change an element’s content in HTML: Simple JavaScript Projects for PracticeTo-Do List: Create a simple to-do list application that allows users to add and remove tasks.Calculator: Implement a basic calculator that can perform simple arithmetic.Image Slider: Create an image slider that cycles through a set of images.
