Navigation

Navigation of this site is accomplished via:

  • Links across the top and bottom of each page
  • Navigation within each page
  • A crumb trail navigation menu above the page content
  • A site map.

Flexibility

This site has been designed using relative Cascading Style Sheets to allow the user to override the default appearance of the site in a number of ways, the most basic of which is to ensure that users can change the font size easily through their browser options.

Font size

At GCHQ we considered the need of people to see larger fonts sometimes and therefore visitors can dynamically change the font sizes in their web browser in one of two ways:

  • press down the CNTL button and whilst using the mouse wheel to increase or decrease
  • from the browser menu bar select View - Text Size and select a size from the list

Alternatively, use a browsers Zoom feature to increase the size of content on your screen by simply pressing Ctrl with + to increase, and Ctrl with - to decrease.

PDF documents

While wherever possible we have provided an HTML version of content on this website, some content is provided in Adobe Acrobat PDF format. For information on how to access this content with specialist browsers please visit access.adobe.com
