Unlock local storage for mobile Web applications with HTML 5

HTML5 is a popular technology for very good reasons. It brought desktop application-like capabilities to the web browser, not just on the desktop, but also on mobile devices. In this five-part series, you will learn about popular HTML5 features. In each part, you will also get to experiment with code that showcases these features to illustrate how they work on both desktop and mobile browsers.
Prerequisites
In this tutorial, you will develop a web application to showcase the Local Storage API. The code used in this tutorial covers core web technologies like HTML, CSS (Cascading Style Sheets) and JavaScript. To test the application on desktop and mobile devices, it is recommended that you use the latest web browser versions.
Local storage 101
As websites became more dynamic and data driven, the need to store data on the client side increased. In many scenarios, web applications need to manage their own state and data, whether

Combine HTML5, geolocation APIs, and web services to create mobile mashups

HTML5 is a popular technology for valid reasons. It brought desktop application-like capabilities to the web browser — not just on the desktop but also on mobile devices. In this five-part series, you will learn about popular HTML5 features. In each part, you will also get to experiment with code that showcases these features to illustrate how they work on both desktop and mobile browsers.
Prerequisites
In this tutorial, you will develop a web application to showcase the geolocation API. The code uses core web technologies like HTML, Cascading Style Sheets (CSS), and JavaScript. To test the sample application on both desktop and mobile, we recommend using the latest web browser versions.
The basics: Getting a fix
The geolocation API provides a standardized interface for users to share their location with trusted websites. It allows a website to retrieve geographical location information of a user, like their latitude and longitude. This information can be

For example, with the 2020 SARS-COV-2 (COVID-19 or “Novel Coronavirus”) crisis, federal and local governments may be rolling out broad programs, but cooperation at the local level is usually the most effective way of getting help to where it is most needed as quickly as possible. Traditional social media is one way of communicating within a community, but this is often not sufficiently structured to enable rapid discovery of help needed.
In the current crisis, we have already seen shortages of local food, medical equipment, and other supplies. In addition, the recommended (or required) self-isolation and social distancing measures can compound the problem by preventing people from easily getting to locations with the
