These skills enable students to structure web content effectively, laying the foundation for sophisticated web design and development. A web application’s backend is in charge of data processing, application logic, and connections with databases or other services. Back-end functionalities of web applications are often built using server-side scripting languages such as PHP, Python, Ruby, Java, and others.

Just like with software, websites need to be tested and debugged before they’re ready to go live. That means developing test cases and ensuring that the website code follows the client’s QA/QC procedures. Until now, the web development team will have put in placeholder images and text in the website design until the real content is ready to be inserted. In the design phase, the dev team begins to create something like an actual website.

After mastering the essentials of vanilla HTML, CSS, and JavaScript, you should learn about client-side web development tools, and then consider digging into client-side JavaScript frameworks. You should also consider learning the basic concepts of server-side website programming. Module 2 equips students with advanced skills in HTML, focusing on creating, hosting, and accurately indexing links and images to enhance web page functionality and aesthetics. Students will learn how to convert unique characters into UTF8 Unicode, ensuring global compatibility and accessibility. This module also delves into crafting and publishing essential HTML elements such as lists, and teaches the intricacies of writing and nesting HTML tables and their content.

At this point, the web development team may work with the client to adjust word counts and character limits for menus and ensure that image and video files look full size.
