ACCESSIBILITY

Understanding accessibility

Accessibility entails providing access to the information contained on a webpage regardless of the physical limitations (visual, hearing or physical impairments), technological limitations (slow connection, old browser, slow screen, etc.) or surroundings of the users.

Aim of Grupo Obras Especiales.

Currently, there are millions of people with some kind of impairment who find it very difficult to browse a website. Therefore, when developing our website, we aimed to make an efficient contribution to removing accessibility barriers and designing a website that is accessible to the greatest number of users possible.
With this aim in mind, we have followed the Accessibility Guidelines established by the WAI (Web Accessibility Initiative) and have applied the standard formats recommended by the W3C (World Wide Web Consortium).

Checkpoints

In this respect, the main measures adopted include the following:

Browsing

Every attempt has been made to ensure the browsing experience is logical and intuitive throughout the site, applying the same structure to all the pages:

• Main browser bar with links to the main sections of the website.
• A central area that shows a path indicating to the user at all times the section and sub-section they are currently in and the information contained therein.

Keyboard shortcuts

Keyboard shortcuts or access keys are combinations of keys that allow you to access the website contents directly without using the mouse.
The way in which the keyboard shortcuts are activated depends on the operating system and browser. The most frequent ones are:

• In Windows systems, with Internet Explorer browsers, type the following sequence: ALT + SHORTCUT + ENTER
• In Windows systems with Mozilla type browsers, type the following sequence: ALT + SHORTCUT
• In MAC systems, the sequence is: CTRL + SHORTCUT

The website can be browsed using the following keyboard shortcuts

• 0 Key -> Direct access or shortcut to the home page
• 1 Key -> Direct access to the section "The Group"
• 2 Key -> Direct access to the section "Technical and human resources"
• 3 Key -> Direct access to the section "Clients"
• 4 Key -> Direct access to the section "Our commitment"
• 5 Key -> Direct access to the section "Projects"
• 6 Key -> Direct access to the section "My projects and sites"

Note: keyboard shortcuts are not available on Netscape 4, Camino, Galeon, Konqueror, Omniweb, Safari (earlier versions than 1.2), Opera Windows/Linux (earlier versions than 7.0).

Links

Where required, links contain a description using the attribute “title”, clearly indicating the target of the link.
Furthermore, as far as possible, the presence of links to javascript functions has been avoided.

Visual design

This website uses cascading style sheets (CSS) to present the information, facilitating its access and correct display in different environments.

Images

All images contain a brief description through "alt", "longdesc" or "title".
Images used purely as decorative elements will incorporate blank descriptive texts.

Fonts

Relative font sizes have been used, which can be configured by the user to facilitate reading of contents on the website.
To increase or decrease the font size, just follow these steps:

• In most browsers, access the menu "View".
• Select "Fonts".
• Choose the desired option.

Accessibility level

All webpages have been validated as XHTML 1.0 Transitional and CSS 1.0 and accessibility has been analysed with the TAW tool, attaining the double-A level of accessibility (AA).
We have confirmed that this website displays correctly in different versions of the major browsers used (Internet Explorer 5.5 and higher, Mozilla, Opera).
However, we know that the mere fact of complying with all these criteria does not guarantee that access to our contents is simple. So, we would invite you to send us your suggestions at the following address: info@obrasespeciales.com
