Web development is the process of creating, designing, and maintaining websites and web applications that are accessible via the internet. It involves both the front-end (client-side)—what users see and interact with—and the back-end (server-side)—which handles data processing, storage, and server communication.

Front-end development includes technologies such as HTML, CSS, and JavaScript, which are used to build user interfaces, layouts, navigation, and ensure responsive design across devices. Popular frameworks like React, Angular, and Vue.js enhance the functionality and interactivity of websites.

Back-end development involves server-side programming using languages like Python, PHP, Java, Ruby, or Node.js, and managing databases with systems such as MySQL, PostgreSQL, or MongoDB. It ensures secure data handling, user authentication, and server logic execution.

Web developers also work with tools like Git, APIs, content management systems (CMS) like WordPress, and deployment platforms such as AWS, Firebase, or Netlify.

In today's digital age, web development is crucial for businesses and individuals to build an online presence, enhance customer engagement, and provide digital solutions. It requires a mix of technical skills, creativity, and problem-solving abilities.
