Web Site development

Introduction
In our country and across Europe have entered the cell markedly in our lives and, currently, the market seems to point towards an increasing convergence of fixed-mobile services and with the same content use whatever means by which you access Internet.

While it is still to solve the problem of high costs of connection, the tendency to use mobile devices for surfing the Web is witnessed by two main factors:

an increasing number of sites such as search engines or portals (eg Google, Yahoo, eBay) have made available a mobile version of the site.

Google Mobile ( www.google.it/mobile), for example, is the platform that the search engine has already made available and through which you can leap from a personalized home page, access to services such as reading mail on Gmail, the titles of the main sources of news, weather and stock prices, as well as use of traditional search functions.

ICANN has launched the new domain. mobi.

The suffix. Mobi, sponsored by mTLD consortium ( www.mtld.mobi) will serve to identify their own web pages developed to be accessible from any mobile device.

Mobile Web Best Practices 1.0

In the above, plus the Mobile Web Initiative del W3C in the words of Tim Barners-Lee, there is "the goal of making the Web truly navigate through mobile devices." The MWI is, therefore, a working group dedicated to the development and definition of best practices for the Web usable via mobile devices has made it a primary objective the establishment of a collection of recommendations addressed to all those involved in the process of designing , creation and publication of a mobile site. In line with this objective, the MWI has recently released the document Mobile Web Best Practices 1.0 (o MWBP).

Given the great variety of devices and browsers exist, to draft the recommendations, the MWI established the basic features of a mobile device:

120 pixels wide screen
Support for XHTML Basic Profile
ability to represent JPEG and GIF 89th (ie non-interface, non-transparent and non-animated)
ability to display color palette web safe
support for CSS 1
ability to manage pages weighing up to 20Kbytes

These characteristics identify a device model relatively poor: this choice is in line with the goal of universality of the Web has always been a priority for W3C. The document is, in fact, opened the direct link with the Web Content Accessibility Guidelines (WCAG) guidelines on accessibility of Web content.

Defined the scope, the document states its main goal: to improve the user experience of Web sites for mobile devices.
By focusing on usability, rather than on technical aspects, the MWI is concerned to identify a model of user behavior and clarify the needs of users of the mobile web. In general, these users have immediate needs and linked to specific targets, often dependence on the result that the most common behavior is to seek relevant information in a short time. Second, browsing via mobile is for the purpose of pure entertainment and serves to bridge the expectations and downtime. From a different point of view, detects an objective difficulty in the connections: the wireless access is often slow and unreliable for a cable connection. Finally, from an ergonomic perspective, it also noted the greater difficulty of interaction with the device is being input is in reading the contents.

Given these assumptions, the list of MWBP lists 60 recommendations that can be grouped into the following categories:

General behavior
Navigation and links
Page layout and content
Definition page
User Input

In some cases, the recommendations are very precise and strictly related to the type of device, in other cases, however, reproduce closely the WCAG, guidelines relating all'eccessibilità, Genaral and principles of usability.

Compliance with the recommendations spelled out in the MWBP are the basic starting point to adopt the mobileOK mark, a sort of self similar logos WAI Level A, WAI Level Double-A e WAI Level Triple-A planned for accessibility.

Meaning, requirements and procedures for acquisition of the label is illustrated in the document W3C mobileOK Scheme 1.0.

Web Designer Sara, ensure standards compliance means that the code developed is easily adapted for use on mobile devices, keeping as much as possible unchanged content and functionality.
