HTML5 Web Applications

2-day Advanced HTML5 Course Programming Web Apps — H5A

HTML5 Web Development Training Course Overview

This HTML5 course provides 2 days hands-on training in how to develop and program fully interactive websites and web applications, using the HTML5 standard.

This HTML5 course is designed for programmers and developers who want to exploit the new HTML5 APIs (application programming interfaces) — to provide, extend or replace existing client-side, server-side and AJAX-based interactivity.

This HTML5 course explains the purpose of the new APIs, shows you how to implement them in current browsers, how to support legacy browsers and offers best practice advice on when/how to implement evolving parts of the HTML5 standard.

Special care is taken to provide sufficient time and realistic use cases for hands-on exercises. Most of the time devoted to each quarter-day course module is committed to task-driven practical work in which students are asked to construct complete, if simple, working applications. These applications are gradually built into the kind of suite you might find on the website of strongly internet-focused (e-commerce) business.

Successful completion of this HTML5 training course will eventually lead on to more advanced HTML5 Workshops — overwhelmingly hands-on, project-based, workshops focused on integration with the server-side backend and on mobile applications.
