Introduction to Web Development Using HTML 5 (Philippine Edition) is a comprehensive beginner-to-intermediate textbook tailored for learners in the Philippines and similar educational contexts. It teaches modern web development using HTML5 with a hands-on approach, building from basic page structure to advanced HTML5 features such as multimedia integration, responsive content, APIs (like geolocation), and interactivity. The content is largely based on the international edition by Kris A. Jamsa, but the local edition may include contextual examples and teaching support suited for Philippine schools and IT/CS courses.
