Web development course in chennai

Front-end development focuses on how a website looks and feels to the user. It includes designing pages, layouts, colors, menus, and forms. This part is built using web languages that handle the visual structure and user interactions. On the other hand, back-end development is about what happens behind the scenes. It manages how data is stored, how user requests are processed, and how the website connects to a database. This part usually involves server-side programming and data handling tools.

I use a responsive design approach by applying media queries in CSS. This allows the layout to adjust based on the device’s screen size. I also test on various screen resolutions to make sure everything looks and functions correctly.

HTML5 introduced many useful features like built-in video and audio tags, the canvas element for graphics, and better form controls. It also improved browser support and made it easier to create interactive websites without needing extra plugins.

APIs allow websites to interact with other systems or services. For example, a website can use an API to show real-time weather updates or post data to a database. I often use REST APIs and tools like Fetch or Axios to get or send data between the client and server.

I compress images, reduce the size of CSS and JavaScript files, enable browser caching, and avoid loading unnecessary scripts. These steps help reduce loading time and improve user experience.

When a user clicks something on a website, the browser sends a request to the server. The server processes this request, gathers the necessary data, and sends it back to the browser. The browser then displays the result for the user to see.

I use HTTPS for secure connections, validate and sanitize all user input to prevent malicious code, and protect sensitive data with proper authentication methods. I also keep software and dependencies up to date.

Git helps track every change made to the code. It allows developers to work on different parts of a project without interfering with each other. With GitHub, we can store code online, manage updates, and collaborate easily.

I check the site on different browsers and devices, test all links, forms, and buttons, and make sure the design looks right. I also test how fast it loads and make sure there are no errors in the code or broken features.
