Immagine accessibilità web

The website has been designed and realized for maximize the user experience and the web usability. The web page design and realization follows the standard ISO 9241 part 151 criteria (Guidance on World Wide Web user interfaces).

The website does not present any barriers for users:

- with sensory impairments:

- with motor disabilities;

- with cognitive limitations or other neurological problems.

To this end, developing this website the WAI (Web Accessibility Initiative) recommendations of the W3C consortium ( have been followed thoroughly.

The WCAG 2.0 (Web Content Accessibility) Guidelines have been executed, as established by the latest  regulations, in compliance with the AA level.

On the W3C website various informational documents can be found, as well as links to the automated verification service (partial). The WCAG2 website provides part of the documentation in Italian, too.

The company is subject also to the Law number no. 4 of 9th January 2004, known as "Stanca Law", and subsequent  implementation Decrees. 

The complete current regulations can be found on the website

The 61/2013 Circular of the Agency for the Digitalization of Italy, revised by the 1/2016 Circular of the Agency for the Digitalization of Italy, has been used as reference regarding the obligations of the public administrations as far as web accessibility is concerned.

Following the criteria published in the document Criteri e metodi per la verifica tecnica e requisiti tecnici di accessibilità per i contenuti e i servizi forniti per mezzo di applicazioni basate su tecnologie web (Criteria and methods for the technical verification, technical accessibility requirements of contents, and services provided with web technologies), hereby we illustrate the 12 technical requirements requested and their application in this website:

​1​Textual Alternatives

An equal textual alternative to non-textual contents must be provided

​Requirement fully respected
​2​Multimedia Contents

An equal textual alternative to all multimedia contents must be provided​

​No multimedia content is present in the website

The contents can be presented in different modalities without losing information or structure​

Stylesheets aside, the contents are comprehensible and a correct reading sequence is defined clearly​


Simplifying the vision putting the focus on the contents​

To  give information, request answers, or as a distinction not only colour has been used, respecting the contrast ratio of​ 4,5:1. Only full colours, without shadings, have been used.

Texts can be zoomed in until 200% without assisted reproduction technologies and any loss of content and functionality. The only text used as image is the company's logo.

​5Keyboard Access

Make all the features accessible on keyboard​

​The standard Access Keys listed below** can be used to move the focus, control the surfing, and the access to the contents.


Adequate amount of time for access


Provide the users with the adequate amount of time to read and use the contents​

There are no time-bound contents, except some real-time data on food services (waiting time). There are no automatisms for the information display.​


Epileptic seizures

Avoid pages that can cause epileptic seizures​

The web pages do not content anything that flashes for more than three times per second.​


Offer users surfing support, as well as help searching the contents and determine their position on the website and in the pages​

Every page has a title describing the topic and the purposes of the page, as well as the different sections inside them. Users can move between the different sections with the mouse or the Access Keys, in the latter case preserving the logical order and the navigation sequence.​​ The focus is always visible if the keyboard is used.

Links are mostly underlined.​

​9ReadableMaking textual content readable and understandable

The language is modified automatically for every page based on the language set in the users' browser.​


Create web pages that look and act in a predictable manner​

The focus shift do not change automatically the context, and the main surfing mechanisms remain unchanged and repeat inside the entire website. There are no similar components with different functions.​


Assistance inserting data and information ​

Help the users avoid mistakes and help correcting them​

Pages that entail data input from users imply control mechanisms installed to identify and prevent any errors, as well as give suggestions ad tabs to make the data input more simple and clear.​


Guarantee the maximum compatibility with the users's software and the assisted reproduction technologies

A considerable effort has been made to ensure the website access with the most common browsers. The compatibility has been tested with:

IExplorer from ver.8 onwards

Mozilla from ver.8 onwards

Chrome from ver.16 onwards

Only and exclusively these technologies have been used:

HTML from ver.4.01 onwards

XHTML from ver. 1.00 onwards

CSS from ver. 2.0 onwards


In accordance with the requirements, the use of HTML 5 e CSS3 and responsive of fluid layouts has been excluded.


* As established by the legislation, the AA levels of compliance checks have been realized on a sample of pages, as defined by the Ministerial Order of 5th July 2005, that is the home page, the pages linked in the home page, the pages containing different types of modules, and a 5% of various types of pages different from the previous ones.

N.B. Depending from the browser used, the use of the Access Keys has different modalities. The Sharepoint technology has the possibility to Activate or Deactivate a native Access Modality.

The surfing of the elements on this website that involve a strong degree of interaction can be fulfilled with the use of keys combinations recommended by the Accessible Rich Internet Applications (ARIA) standard.

Specifically, in the browsers that support this standard it is possible to use:

- the TAB key to place the focus on an interactive element as part of the tabulation order of the entire page;

- use the ARROW keys to move the focus trough the different controls of the interactive elements

- use the ENTER key to activate the control on the current focus;

- use the TAB key to move between the control groups or leave the interactive element

Other features:

- Menus have been designed through lists not ordinated <ul>, therefore the readability of the stylesheets has not been lost, even on deactivated ones. 

- "Nonscript" tag have been use limitedly, as the jQuery interface allows to manipulate the pagecode through the uploading script.

- Users can change the dimension of the base font (every font used in menus, boxes, etc. will adapt proportionately) as they please, with the standard function of their browsers (that is, not with specific fnction designed for the website).

- While the html fully respects the accessibility standards, some functions connected to the integration system (SharePoint) and the CSM management may be defective in some points, but not compromising the access to the contents. 

- Although a liquid layout has not been used, the pages can adapt easily to windows between 800px and 1920px with the base font.
