What is Web Development?
Web development entails the creation and maintenance of websites and web applications. Various aspects like designing, coding, and implementing the functionality of a website are essential components of web development. Web developers utilize several programming languages, frameworks, as well as tools to build user-friendly, interactive websites that meet the needs of businesses or individuals.
Web development encompasses both front-end and back-end development. Front-end development focuses on the visual and interactive elements of a website that users see and interact with. It involves designing the layout, implementing user interfaces, and ensuring the website’s responsiveness. Back-end development, on the other hand, deals with the server side of the website, handling databases, server configuration, and ensuring smooth functionality.
Essential Skills for Web Development
To excel in web development, several essential skills are required. Besides the below-listed skills, web developers should have a good understanding of responsive web design principles and version control systems like Git, along with a knowledge of web development frameworks such as React, Angular, or Vue.js. Now, let’s explore the three fundamental skills every web developer should possess.
- HTML (Hypertext Markup Language)
HTML is the backbone of web development. It is a markup language used to structure the content of web pages. It uses various elements and tags to define the structure, headings, paragraphs, images, links, and other elements of a web page. Web developers use HTML to create the skeleton or basic structure of a website.
HTML is relatively simple to learn, and its syntax is straightforward. Every web developer must have an understanding of HTML, as it forms the foundation of web development and is essential for building well-structured, accessible websites.
- CSS (Cascading Style Sheets)
CSS is a style sheet language used to describe the presentation and appearance of a web page. It is utilized to manage the design, color scheme, font selection, and other visual elements of a website. CSS works hand-in-hand with HTML, allowing web developers to create attractive and visually appealing websites.
With CSS, web developers can not only define styles, such as font sizes, colors, margins, and positioning but also apply them to specific HTML elements or groups of elements. This separation of content (HTML) and presentation (CSS) allows for easier maintenance and consistent styling across multiple pages.
- JavaScript
Websites with the dynamic functionality and interactivity of JavaScript, which is a powerful scripting language, become more engaging to users. It enables web developers to create interactive elements, handle user events, manipulate Document Object Model (DOM), and perform various client-side tasks.
JavaScript is widely used for tasks such as form validation, creating interactive forms, implementing sliders and carousels, and making asynchronous requests to servers (AJAX). With JavaScript, web developers can enhance the user experience by creating responsive and interactive elements that engage users and make websites more dynamic.

Knowledge of Front-End Web Development
When it comes to web development, there are two key areas of focus, namely front-end and back-end development. While it is not necessary to learn both front- and back-end web development to make a career in this field, having a basic understanding of both can certainly be beneficial.

Front-End Web Development
Front-end web development refers to the development of the client side of a website. It entails designing and developing the user interface and ensuring that a responsive and user-friendly website is created. The three primary technologies used in front-end development are HTML, CSS, and JavaScript.
CSS Frameworks
These pre-written code libraries help developers create websites, quickly and efficiently. The set of CSS styles, templates, and functionalities contained within can be easily integrated into a website. CSS frameworks offer several advantages to web developers; saving up on time and reducing the effort required to create a website from scratch are just a few of them. Bootstrap, Foundation, and Materialize are some popular CSS frameworks used by web developers.
Angular
Developed by Google, the popular front-end development framework, Angular, offers features like data binding, dependency injection, and component-based architecture. Created by Facebook is React, another popular framework that is known for its simplicity and speed. Providing a simple and intuitive approach to web development is Vue.js, a lightweight and easy-to-use framework.

Skills for Back-End Web Development
Back-end web development refers to the development of the server side of the website. It entails the creation of the server-side application that handles requests from the client-side and performs various operations. Server-side languages and databases are the two primary technologies used in back-end development.
Server-Side Languages
These are programming languages used to create the server-side application. They are responsible for handling the requests from client side, processing data, and sending the results back to client side. PHP, Python, and Ruby are some of the popular server-side languages used by web developers.
Used by millions of websites worldwide, PHP is a popular server-side language that is simple and easy-to-learn, providing several features and functionalities. Another popular language known for its simplicity and ease of use is Python, and it is widely used in web development, scientific computing, and artificial intelligence. Ruby is commonly used in web development owing to its simplicity and elegant syntax.
Databases
Serving as the foundation of any web application, databases are used to store, manage, and retrieve data from a website. Relational and non-relational databases are the two primary types of databases used in web development.
With a structured approach to store data, relational databases are designed to manage large amounts of data efficiently. MySQL, PostgreSQL, and SQL Server are some of the current and popular relational databases. Whereas, non-relational databases, using a non-structured approach to store data, are designed to handle large amounts of unstructured data. Popular non-relational databases include MongoDB, Cassandra, and Couchbase.
Grasp on Full-Stack Web Development
Off late, full-stack web development has become an in-demand skill in the tech industry. With the growth of mobile- and web-based applications, there is a rising need for developers who can build complete solutions from the ground up. Full-stack web development entails a combination of both front- and back-end web development, involving the building of both the client- and server-side components of an application.

A grasp on full-stack web development allows developers to work more efficiently and independently. With a complete understanding of the entire web development process, they can work on both the front- and back-end of an application without relying on other developers. This not only improves their productivity but also makes them a valuable asset to any team.
