Description:
An elegant chrome extension dashboard which incorporates several widgets like Analog clock, calendar, weather, Gmap, Music-Player, to-do list, stocks. Bootstrap is also used to apply quick styles, I have used bootstrap grid to contain the widgets so that it can be responsive, container-fluid class is also used to contain and aligned the elements inside, row class is used to keep the widget in a row. All of these feature's source code is given assets folder or directly in the index.html (Which uses iframe). All the APIs mentioned below are open-source(does not require to create an key explicitly for a particular user or developer) and every features are being handled at the client side, this chrome extension does not rely on any complex backend features. You can also set a video file as a background apart from image file like jpeg, gif etc. This project does not collects any user data as it completely relies on the client side handling. However it does contain some third party open source APIs which may collect the data if mentioned at their privacy policy.
