explains HTML5 Local Storage

HTML5 local storage is structured on named key/value pairs, unlike other databases that make use of SQL-intense applications. Data is stored based on a named key. After that, data may be retrieved using the same key. The named key is in a string format. The data may be of any type supported by JavaScript, such as Booleans, strings, floats or integers. Even so, the data is generally saved as a string. If users store and retrieve anything other than strings, they must make use of functions, such as parseFloat() or parseInt(), to coerce the recovered data to the expected JavaScript datatype.
From the JavaScript code, HTML5 local storage may be accessed through a localStorage object on the global window object. The localStorage object stores the data without any expiration date. The data is not wiped, even after closing the browser, and may be accessed at any time. Because it is client-side, stored data is based on the browser that is used.

Definition - What does HTML5 Local Storage mean?

HTML5 local storage is a component of the Web storage application programming interface. It is a method by which Web pages locally store named key/value pairs inside a client's Web browser. Similar to cookies, this saved data exists - even when you close a browser tab, surf away from a current website, exit a browser tab or close a main browser. Unlike cookies, this data is not carried to the remote Web server unless it is sent manually. Because HTML5 local storage is natively integrated into Web browsers, it is available without third-party browser plug-ins. It is described in the HTML5 specifications.

Local storage is mainly used to store and retrieve data in HTML pages from the same domain. Even after restarting a browser, the data can be recovered from all windows in the same domain. This type of storage offers numerous options for Web apps.

Browsers, such as Firefox 3.5+, Internet Explorer 8.0+, Chrome 4.0+, Safari 4.0+, Mobile Safari (iPhone/iPad), Opera 10.5+ and Android 2.0+ support HTML5 local storage.

explains HTML5 Cookie

An HTML5 cookie generally serves a similar functionality as that of a standard website cookies, but it's much faster and more secure. It was designed to eliminate the security issues that come with a traditional cookie. An HTML5 cookie stores the data directly on the browser in two distinct forms:


  • Session storage saves the data until the session expiry
  • Local storage is persistent storage
This system enables confidential transactions to be securely removed, offline access of applications, less header data in communication with the primary website and larger capacity than traditional cookie storage.

Definition - What does HTML5 Cookie mean?

An HTML 5 cookie is a cookie-like storage options available in HTML 5. It consists of browser-based local storage and session storage, which is created and accessible by the Web page itself.

An HTML5 cookie is also known as HTML5 Web storage and is an alternative to the commonly used browser cookie.

explains HTML 4.0

HTML 4.0 extended the previous HTML 3.2 revision into powerful capabilities including ideas never implemented from HTML 3.0 draft. On December 1999, HTML 4.0 was replaced by HTML 4.01 as a minor update correcting minor problems. Thus, HTML 4.01 is the final standard version recommended by W3C.

HTML4 (or HTML 4.01) is constantly evolving. The next revision is HTML 5.0 which has been debated for years and has a very complex process for implementation, though many browsers currently support some of the newer HTML5 features. While HTML 4 will be phased out eventually, it while be a while before everything moves to HTML5.

Hypertext Markup Language revision 4.0 (HTML 4.0) is a markup language that represents the structure and presentation of web pages. HTML 4.0 was published on December 1997 as a W3C Recommendation.

In addition to previous revisions of HTML, HTML 4.0 supports style sheets, scripting languages, object support, more multimedia options, and improved accessibility for users with disabilities, among other features.

5 Things You Need to Know About HTML5

Takeaway: The rapid adoption of HTML5 - the successor to the now long-in-the-tooth HTML4 - is allowing programmers to create some impressive websites.

It seems like HTML5 has been around forever, but it’s technically not even a standard (the specification recommendation is scheduled for 2016, so it will be years before it’s officially approved). Because most browsers already support many of its features, smart developers and programmers are taking advantage of the myriad ways that it improves their coding and enriches many popular websites.

Whether you’re a programmer or someone who enjoys the wonders that HTML5 lets website designers create, the new markup language has a lot to offer. Here are five cool features of HTML5:

Geolocation Is Where It’s At

"Would Like To Use Your Current Location?" How many times have you seen that on your phone in the last few years? It’s HTML5’s convenient yet possibly intrusive geolocation feature, and you’re going to be seeing it even more. With an increasing percentage of traffic coming from mobile devices (the United States is at 12 percent, while India is more than 60 percent), it’s no wonder that many websites are using HTML5’s geolocation feature to hyper-localize a user’s Web or app experience. This site should pinpoint your position extremely well on a smartphone and surprisingly well on a desktop.

HTML5 Will Improve Your SEO

Want to improve your Google page rank? Use HTML5. According to searchengineland.com, using HTML5 is a "godsend" for SEO, especially for sites that use a lot of Flash, since "searchbots will be able to crawl your site and index your content. All of the content that is currently embedded in animations will be readable to search engines. In basic SEO theory, this one aspect of HTML5 will do wonders for your website’s ability to drive organic search traffic." HTML5 also makes it easier for programmers to use audio and video on their sites, and search engines favor media-rich pages.

It’s a Blank <Canvas> for Gaming

Programmer Josh Goldberg faithfully recreated Super Mario Brothers, a cherished childhood game, by using HTML5 and the <canvas> element. His impressive piece of programming went viral, attracting more than 300,000 unique, Mario-loving visitors per day. Unfortunately, he didn’t check with Nintendo before undertaking the year-long task of recreating the game. Mario’s owner, Nintendo, stated that the game was "illegal" and should be taken down immediately, as it violated their copyright. The site was taken down on November 1, 2013 - but not before nearly 2.7 million visitors had a chance to play the game. WebdesignerDepot.com has a list of 25 "incredibly addictive," legal HTML5 games. HexGL, a futuristic racing game, has stunning graphics for a browser-based game.

Local Storage Means No More Cookies

Cookies have worked (reasonably) well for programmers since Netscape invented them in 1994, but they have significant drawbacks, including the need to be sent with every HTTP request, lack of encryption and size limitation (about 4k). While technically not part of the HTML5 standard (it was split off from HTML5 a couple of years ago), local storage overcomes the cookie’s limitations by storing data locally in the browser. The data is never sent to the server; no third-party plugins are required and the 5MB size limit is more robust. IBM has a cool sticky note example of local storage, while the curious should visit Dive Into HTML, which goes deep on local storage.

Create a Garage Band Using Jam With Chrome

Invite some friends and form a band with Jam with Chrome, an HTML5 Web app with 19 different instruments, amazing graphics (the vibrating guitar string effect is mesmerizing) and surprisingly good sound. This Chrome-only game takes full advantage of HTML5 features, like Web Audio (which creates better sound from the browser), Websockets (to let band members interact in real time) and the Canvas feature, which allows for better graphics (including the aforementioned vibrating string effect).

Web developers don’t seem to care that HTML5 is not a standard. In fact, the entire Web community is benefiting while developers happily use its rich new features to develop amazing websites and games.
