dynamic chessboard frame

Look at the new dynamic chessboard frame provided by pgn4web: a chessboard that adjusts itself to use the available space. The size of the chessboard is maximized and the layout of the surrounding text adjusts to the horizontal or vertical shape of the available frame: this is particularly useful when using the dynamic frame fullscreen with mobile devices and rotating the device's screen. A live broadcast mode is also supported. Try opening the frame in a full window by clicking square H5, then resize the browser window and notice how the chessboard frame adjusts to the available space.
