Supported browsers:

OpenPanzer respects latest W3.org HTML5, CSS3 specs and browser specific specs are kept to a minimum -> null. Base supported javascript engine is V8 open source engine. Code should be kept to basic features of ECMAScript 5.

OpenPanzer works in recent Google Chrome, Mozilla Firefox, Safari and Opera. OpenPanzer works on Android (tested on 2.2, 2.3, 4.x) and iOS devices (5.0+).

Internet Explorer will probably work with version 11 but extensive code changes for IE aren't a priority.

Development notes:

OpenPanzer doesn't use any extra javascript libraries (like jquery, node etc), and should be kept like this. Styling DOM elements should be done in their CSS files. Adding style for static elements in the code shouldn't exist. All positioning of DOM elements should be done in CSS files. Bottom line: if something can be done in a css file then there it should go not in the javascript code. Code additions should follow the coding style used so far (for object creation etc).

Main testing is done on Google Chrome and Firefox under Linux.

Running the code locally in Google Chrome requires --allow-file-access-from-files option when starting Google Chrome.
