Wherever You Go, There We Are: the Geolocation API
No matter how you go mobile, you can meet your user’s needs. Recommendations based on location are plentiful, particularly on native apps. But don’t fret, agencies with mobile websites: you can also get in the location customization game.
Geolocation is not part of W3C HTML5 or the WHATWG HTML. However, W3C has published specifications to standardize this API to retrieve the geographical location information for a client-side device.
