Mobile web development, also known as responsive web design, is an approach to web design aimed at crafting sites to provide an optimal viewing and interaction experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones). A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries.

ASP.NET Core

Xamarin

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).
