The iPhone has generated quite a stir about creating web apps as this seems to be the only way to develop applications for Apples newest toy. I have to admit that it has me wondering just what languages these apps are developed in (Java script?) and are there any special HTML/CSS considerations when dealing with web apps rather then web pages.

The iPhone runs the Safari browser so web apps written for the iPhone are just like web apps written for any other purpose, using a combo of HTML, JavaScript and CSS. I'm pretty sure that the iPhone Safari implementation still lacks support for Flash and Java Applets. (Of course, server-side Java is unaffected by the lack of client-side Java support).

The trick with writing iPhone apps is dealing with the different client events, that don't exist in a normal browser, resulting from the touch-screen interface.

and are there any special HTML/CSS considerations when dealing with web apps rather then web pages.
That's probably a more appropriate question for the Servlets forum, but one of the biggest gotcha's that seem to trip people up when writing web apps (as opposed to pages showing pictures of kittens) is the use of page-relative URLs for resources such as images, script files and style sheets. Such URLs should be server-relative in order to avoid problems when the URL known to the browser is a mapping rather the location of a physical resource.
