HTML5 Offline. Web browsers were originally simply viewers for static HTML documents. Since HTML2, browsers have had the capability to capture simple user input with forms and send it to a database on the Internet.

I’ll also show you how to build an example application that implements an offline-capable tool for saving geo-coordinates (geolocations). This app runs on any devices that supports HTML’s offline features, including Firefox (currently v14) , Opera (v12), Chrome (v21), Safari, and Internet Explorer (v9).

For more up to date tips and best practise see my offline web app workshop, published for free on GitHub, which includes a chapter on building an offline news app. Most importantly, my advice on using local databases (WebSQL and IndexedDB) has evolved since writing this article. I now recommend only implementing IndexedDB integration and using the IndexedDB polyfill to support browsers that only provide WebSQL. For the actual integration with IndexedDB I recommend using Dexie.js a Promise-based library that makes integrating with IndexedDB easy and safe.
