It may be that, because you have other special needs or you are elderly, you have problems accessing web content and you some across barriers similar to users with some kind of disability. 

This section contains information on some of the solutions available for people with the most common kinds of disability.

If visual problems prevent you from reading and interacting with web pages, you can get a larger screen monitor or use a screen magnifier.

Below we show you how to change colours, styles and fonts of pages in your browser depending on your needs or preferences:

browser menu options
Mozilla Firefox

Internet Explorer

Tools > Internet options > Button "Accessibility" in the "General" tab > Activate one of the "Omit... " boxes and then go to the "General" tab to personalise

You can configure your computer to high contrast:

  • In Windows, with the key combination Shift or Caps + Alt + print screen key or go to Control Panel, then Activity Centre and you can set the high contrast there.En OS para Mac, id a Accesibilidad y en la sección "Pantalla" activad la casilla "Invertir colores".
  • In Mac OS, go to Accessibility and the "Screen" section, then activate the "Invert colours" box.
  • In Linux Gnome, go to Systems, then to Preferences and then to Appearance, and select one of the high contrast areas.

If you need alternatives for interacting with web pages because you have difficulty moving your upper limbs (hands or arms):

  • You can use a special keyboard or mouse (keyboards with large keys, conventional keyboard with an overlay, a large trackball mouse, button mouse, etc.). 
  • If you need to press various keys at once and you cannot use both hands to do this, you can use the "StickyKeys" function to simulate this key combination with a certain number of presses on a single key. 
    • For example, these keys can be set to carry out particular functions ([CTRL + ALT + SUPR], [ALT + F4], etc.) in Windows by using the StickyKeys function. The combination of the Control + Alt + Supr keys can be achieved by pressing the Shift or Caps key five times.
    • In the GNOME for GNU/Linux environment you can configure the activation of StickyKeys in the keyboard accessibility preferences window. 
    • In the OS for Mac operating system you can activate the options for slow keys or easy press keys in the "Accessibility" window in the "Keyboard" section.
  • You can change the functions of all the buttons on your pointer device, enabling you to assign the most important functions to the buttons that are most useful to you, as well as configure the movement speed of the pointer device and adapt it to your handling capabilities.
    • In Windows, you can do it from the Control Panel > Accessibility Centre and select the options that best suit your needs in "Easier mouse use".
    • In OS for Mac, you can do this using the various options in the "Mouse and Trackpad" section in the Accessibility window. 
  • You can configure the keyboard to emulate some of the mouse actions:
    • In Windows, you can do it from the Control Panel > Accessibility Centre and select the options that best suit your needs in "Easier keyboard use".
    • In OS for Mac, you can do this using the various options in the "Keyboard" section in the Accessibility window.
