Build a Responsive ZK Web App With Fancy URLs

We all know Java from the old days. We’d write full Java applications with Swing and our worst case scenario was that some users used a low pixel screen like 800×600. That time passed long ago; we have all different type screens now, from mobile phones to very big monitors and even TVs are used as computer screens.
The developing of a UI also changed from normal desktop applications to web applications. With this change, JavaScript and CSS are now the basic languages to know if you want to create a web app.
