Screenfly / Test Your Website at Different Screen Resolutions. Socket.IO. Introducing WebSockets: Bringing Sockets to the Web. The Problem: Low Latency Client-Server and Server-Client Connections The web has been largely built around the so-called request/response paradigm of HTTP.
As example of its capabilities, the File API could be used to create a thumbnail preview of images as they're being sent to the server, or allow an app to save a file reference while the user is offline. Additionally, you could use client-side logic to verify an upload's mimetype matches its file extension or restrict the size of an upload. The spec provides several interfaces for accessing files from a 'local' filesystem: File - an individual file; provides readonly information such as name, file size, mimetype, and a reference to the file handle.
Embedding media in your HTML document is trivial: HTML5 Cross Browser Polyfills · Modernizr/Modernizr Wiki. The No-Nonsense Guide to HTML5 Fallbacks So here we're collecting all the shims, fallbacks, and polyfills in order to implant HTML5 functionality in browsers that don't natively support them.
The general idea is that: We, as developers, should be able to develop with the HTML5 APIs, and scripts can create the methods and objects that should exist. Developing in this future-proof way means as users upgrade, your code doesn't have to change but users will move to the better, native experience cleanly. Looking to conditionally load these scripts (client-side), based on feature detects? See Modernizr. Looking for a guide to write your own polyfills?

Introduction to HTML5 DOMStorage API with Example. HTML5 is a standard for structuring and presenting content on the World Wide Web.
The new standard incorporates features like video playback and drag-and-drop that have been previously dependent on third-party browser plug-ins such as Adobe Flash and Microsoft Silverlight. HTML5 introduces a number of new elements and attributes that reflect typical usage on modern websites. Some of them are semantic replacements for common uses of generic block (<div>) and inline (<span>) elements, for example <nav> (website navigation block) and <footer> (usually referring to bottom of web page or to last lines of html code). Other elements provide new functionality through a standardized interface, such as the multimedia elements <audio> and <video>. In addition to specifying markup, HTML5 specifies scripting application programming interfaces (APIs). What is DOM Storage? DOM Storage is a way to store meaningful amounts of client-side data in a persistent and secure manner.
Scope of DOM Storage. HTML5 Geolocation API Tutorial Latitude/Longitude API. HTML5 has finally pushed the web ahead with many new APIs that were lacking since the inception of HTML.
New APIs like DOM Storage API helps in making better web applications. As part of the specification, HTML5 added set of new APIs under title Geolocation that helps the applications to identify location related information from visiting users. Here is the official definition from HTML5 specification: The Geolocation API defines a high-level interface to location information associated only with the device hosting the implementation, such as latitude and longitude. The API itself is agnostic of the underlying location information sources. The API can be used to get current location (latitude, longitude) of user.
