Web development is the process of creating and maintaining websites or web applications. It involves designing, coding, and deploying web content that can be accessed through the internet.
Common technologies include HTML, CSS, and JavaScript for front-end development, while back-end development often involves languages like PHP, Python, Ruby, or Node.js. Databases such as MySQL, PostgreSQL, and MongoDB are also essential.
Front-end development focuses on the user interface and user experience, involving the design and functionality that users interact with directly. Back-end development deals with server-side logic, databases, and the overall functionality that happens behind the scenes.
Responsive design ensures that websites adapt to different screen sizes and devices. It's crucial for providing a seamless user experience across desktops, tablets, and smartphones, improving accessibility and usability.
Security is paramount in web development to protect websites and user data from potential threats. Developers must follow best practices like input validation, secure coding, and implementing HTTPS to ensure a secure online environment.
