In order to make this website as user-friendly to as many people as possible, several solutions are being worked on.

Text size
Fonts that allow the user to enlarge the text through their browser options have been used.

Equivalent texts
An equivalent text to non-textual elements is provided (for example, through alt, longdesc, title or in the element content). These include: images, graphical representations of text, image maps, photographs, scripts, images used as bullet points in lists, and space or graphic buttons.

Colour codes
All information is transmitted through colours that are also available without colour, for example, through context or by markers.

Page structure
The site is designed with a consistent format for all the content pages: header, left menu column, central content area and right column. This allows the user to become familiar with the respective page structure, making easier use for those who require technical assistance in exploring the site.
