问题 We have an app for an embedded system, and we are developing several apps based on HTML5, CSS3, and some JS libraries, which run on a webkit browser. I was wondering if there are any libraries that implemented on screen keyboard with customizable graphics of keys. It should also be easy to internationalize it.
