HTML5 – the basic approach

HTML5, where does it come from?

HTML – Hyper Text Markup Language – is a mark-up language that was developed back when the Internet was invented in order to be able to suitably structure and transmit documents i.e. web pages. The recipient, a web browser, should be able to interpret and display the HTML document accordingly. From the time the Internet was created this simple principle has basically not changed, but it has been properly beefed up.

Mechanisms and standards for adding dynamic elements to web pages through to so-called “web applications” have been developed over the years. Permanent interaction between the web server and client via the network is required. There are software frameworks and libraries galore. The web browser today is a complex system that handles the content received and, in doing so, generally executes complex program code.

A smooth user interface that quickly goes in depth

When we talk of HTML5 today, we mean the technological substructure of such a web application. On the surface, this can be represented by three parts:

  • HTML(5) still provides the fundamental structure for the web page.
  • SVG serves for drawing graphics elements.
  • JavaScript adds dynamic features to the web page and displays corresponding program logic.

But in fact, there are a number of other components that do their bit depending on the requirements of an application: communication, data processing, display, security. The list of tools and approaches could probably be expanded on a weekly basis; the versions on a daily basis. And this for both the web client and the web server. An HTML5 web application is developed within the dynamic environment of current web technologies. It then will continue to exist there too. Much more than just a few lines of JavaScript code are therefore needed.
