what is web development

Web development involves building and maintaining websites or web applications. In this guide, we will explain what is web development, along with its key components, tools, and types of developers.


Key Takeaways


  • Web development encompasses creating, maintaining, and enhancing websites, involving both front-end (user interface) and back-end (server-side) processes.

  • Key programming languages for web development include HTML, CSS, and JavaScript for front-end tasks, while PHP, Python, Ruby, and Java are crucial for back-end operations.

  • Understanding the various roles of web developers—front-end, back-end, and full-stack—is essential for navigating the web development field effectively.



What is Web Development


Web development refers to creating websites on the internet, encapsulating tasks involved in coding and maintaining web applications. It’s a broad field that includes everything from building a simple static web page to developing complex web applications that interact with databases and provide dynamic content. The key activities in web development involve sophisticated programming for back-end functions and CSS coding for the front-end, alongside project management and often times digital marketing activities.


Web development plays a key role in boosting businesses’ online presence and enhancing user interaction. The development process involves creating both visually appealing and functional web pages that deliver a seamless user experience.


Web developers use various tools and technologies to build and maintain websites, ensuring they are responsive, secure, and efficient. Mastering different aspects of web development enables the creation of interactive web pages that engage users and drive business growth.


Understanding Web Development


Web development is the art and science of creating websites on the Internet, encompassing both simple single-page sites and complex massive websites. It involves a combination of sophisticated programming, content creation, project management, and user experience (UX) design, which are essential skills for developers. The ability to build and maintain a website is crucial for boosting businesses or building apps, as it provides essential opportunities to connect with a vast global audience. Additionally, around 48% of people consider a website’s design when determining a business’s credibility (1). 


Website maintenance, which involves updating content, fixing issues, and ensuring compliance with evolving web standards, is essential for keeping websites functional and up-to-date. Understanding the various components and processes involved in web development enables the creation and maintenance of websites that are engaging, reliable, and secure.


Key Components of Web Development


Web development functions on two main levels: front-end and back-end. Front-end development, also known as client-side development, focuses on the aspects of a website that users interact with directly. This includes front end web development, the layout, navigation, graphics, and overall aesthetics.


On the other hand, back-end development involves managing server-side processes and using different technologies to ensure the functionality of a web application.


In addition to front-end and back-end development, there is also full stack web development, which encompasses both front-end and back-end development. Full-stack developers are skilled in various technologies essential for both sides of development, making them versatile and highly valuable in the web development world.


Anyone looking to create comprehensive and well-rounded web applications should understand these key components.


1) Front-End Development

Front-end development, or client-side development, is the area of web development that users interact with directly, making it crucial for user engagement. Front-end web developers are responsible for ensuring a website is user-friendly, visually appealing, and functional across various devices. In fact, around 79% of users stated that they would not engage with a website that does’t load quickly and display well on their device (2). As such, web developers focus on creating interactive elements that allow users to engage with websites through functionalities such as playing videos, expanding images, and navigating content.


Key technical aspects controlled by front-end development include typography, fonts, navigation, positioning, and responsiveness, largely defined by CSS. Mastering these elements allows front-end developers to create seamless and intuitive user interfaces, enhancing the overall user experience.


Their work ensures that websites are not only functional but also visually appealing and accessible across different devices and screen sizes.


2) Back-End Development

The back-end in web development refers to server-side digital infrastructure not visible to users. Back-end development focuses on behind-the-scenes features that ensure the functionality of a web application. This includes data processing, server management, and ensuring that the front-end functions correctly by managing databases and server-side operations.


Back-end developers need an understanding of databases, server management, and web security. They work alongside front-end developers. This collaboration helps to deliver products to users. The role of back-end development is crucial when storing user-entered data and setting up websites on a server, which involves establishing user authentication and configuring networks and hosting.

These skills ensure that web applications are robust, secure, and efficient.


3) Full-Stack Development

Full-stack development encompasses both front-end and back-end development. It is defined as the combination of front-end and back-end web development. Full-stack developers are considered jack of all trades, skilled in various technologies essential for both sides of development. They work on both the front-end and the back-end of a website, ensuring a cohesive application.


A comprehensive skill set helps full-stack developers optimise website performance effectively. Being a full-stack developer means having expertise in both front-end and back-end development, making them versatile and highly sought after in the industry.


A full-stack developer course can be beneficial for becoming well-versed in web development.


Essential Programming Languages for Web Development


The key programming languages essential for web development include HTML, CSS, JavaScript, PHP, Python, Ruby, and Java. These languages are the building blocks of web development, enabling developers to create visually appealing, intuitive, and interactive websites. Front-end programming languages like HTML, CSS, and JavaScript are used to design the user interface, while back-end languages like PHP, Python, Ruby, and Java handle server-side operations and data management.


Mastering these programming languages is crucial for anyone looking to become a proficient web developer. Leveraging these languages enables developers to build robust and dynamic web applications that provide a seamless user experience.


Each language has its strengths and is suited for different aspects of web development, making them essential tools in a developer’s toolkit.


1) HTML (Hypertext Markup Language)

HTML is used to create and structure web pages. It is crucial for defining the semantic structure of web pages and includes elements such as headings and links. HTML allows developers to create the basic framework of a website, ensuring that the content is organised and accessible.


2) CSS (Cascading Style Sheets)

CSS styles the visual appearance of a website. It allows developers to customise visual elements like colours, fonts, and layouts, significantly contributing to a website’s aesthetic. CSS allows for the creation of responsive web pages. These pages can adjust to various screen sizes.


A style sheet typically includes many rules for each element of the site, setting design parameters for the entire site in one master style sheet.


3) JavaScript

JavaScript adds interactive elements to web pages, enhancing user experience. It is primarily used to create interactive features on web pages, enhancing user engagement and experience. JavaScript typically runs in the client’s browser, providing immediate interactivity and responsiveness to user actions.


JavaScript libraries like React and jQuery simplify cross-browser development and enhance functionality. React is a JavaScript library for building user interfaces, allowing for the creation of reusable UI components. jQuery simplifies HTML manipulation and event handling, making it easier for developers to create dynamic features.


Node.js, a JavaScript runtime, allows for server-side JavaScript, enabling scalable and efficient applications.
