Understand accessibility

Accessibility means providing access to the information on Web sites regardless of physical (visual, hearing or motor impairments), technological (slow connection, old browser, slow screen, etc.) or user environment limitations.


There are millions of people with some kind of impairment for whom browsing a Web site is extremely complicated. For this reason, we have designed our Web site with an eye on efficiently contributing towards the reduction of accessibility barriers and designing a site accessible to the greatest number of users.

With this aim in mind, we have followed the Accessibility Guidelines of the WAI (Web Accessibility Initiative) and have applied the standard formats recommended by the W3C (World Wide Web Consortium).

Verification points

The main measures adopted include the following:


Efforts have been made to achieve logical, intuitive browsing throughout the site, applying the same structure to all pages:

  • The main browser bar with links to the main sections of the Web site.
  • A side menu on the left showing the options available in each section.
  • A central area showing a route to inform users as to which section or subsection they are in and information on the same at all times.

Access keys

Access keys are key combinations which permit shortcuts to the contents of the Web site without having to use a mouse.

The method by which access keys are activated depends on the operating system and the browser. The most common are:

  • On Windows systems with Internet Explorer, press: ALT + ACCESS KEY + ENTER.
  • On Windows systems with Mozilla, press: ALT + ACCESS KEY.
  • On Windows systems with Firefox 2.0: ALT + SHIFT + ACCESS KEY.
  • On MAC systems, the key sequence is: CTRL + ACCESS KEY.

This Web site can be browsed with the following short-cut access keys

  • Key 0 -> Shortcut to home page.
  • Key 1 -> Shortcut to the section "About Tracasa".
  • Key 2 -> Shortcut to the section "Services and products".
  • Key 4 -> Shortcut to the section "Our customers".
  • Key 5 -> Shortcut to the section "News".
  • Key 6 -> Shortcut to the section "Downloads".
  • Key 7 -> Shortcut to the section "Contact".
  • Key 8 -> Shortcut to the section "Accessibility".
  • Key 9 -> Shortcut to the section "Legal notice".

Note: Netscape 4, Camino, Galeon, Konqueror, Omniweb, Safari (below 1.2), Opera Windows/Linux (below 7.0) do not support shortcut access keys.


Links which require descriptions include one via the "title" attribute, clearly indicating the destination of the link.

All possible efforts have been made to avoid links to JavaScript functions.

Visual design

This Web site uses Cascading Style Sheets (CSS) to present information, facilitating access and correct viewing in different environments.


All images include a brief description via "alt", "longdesc" or "title".

Those images used for purely decorative purposes have blank descriptive texts.


Relative font sizes which can be configured by the user have been used to make reading the contents of the Web site easier.

To increase or decrease the size of the letters, proceed as follows:

  • On most browsers, access the "View" menu.
  • Select "Text Size".
  • Mark the desired option.

Level of accessibility

All the pages have been validated with XHTML 1.0 Transitional and CSS 1.0, and accessibility has been analysed with the TAW, tool, achieving accessibility level double-A.

We have checked the correct viewing of this Web site on different versions of the main browsers used (Internet Explorer 6.0 and higher, Mozilla Firefox 1.5 and higher, Opera 8 and higher).

We are aware, however, that merely complying with all these criteria does not ensure easy access to contents. We would, therefore, be pleased to receive your suggestions at: webmaster@tracasa.es.
