We are committed to making our online resources accessible to all users of the site. We aim to continually review our web pages and modify them to ensure that they are accessible for all users. Our content is checked for Plain English and we aim to use a written style that is straightforward and understandable.


We follow a list of accessibility guidelines when designing our website and content these include:

  • Maintain a standard layout and navigation system throughout
  • Use headings, paragraphs, lists and other HTML (HyperText Markup Language) to create a logical document structure
  • Allow visitors to resize all text
  • Use plain backgrounds to improve the readability of text
  • Use foreground and background colour combinations which have sufficient contrast and are not known to cause problems for sufferers of colour-blindness
  • Use alt attributes on all images and ensure that all titles are meaningful
  • Design layouts to work satisfactorily at a range of screen resolutions
  • Ensure all hyperlinks use descriptive and meaningful text, avoiding short-hand language like "click here"
  • Provide internal anchors for visitors using screen readers or similar technology

Controlling text and colours in your web browser

Change text size with zoom

Most web browsers let you increase and decrease the size of text, images, and other web page content with a "zoom" feature. Some browsers let you choose to zoom only the text size.

To change the zoom in most browsers, press the following two keys at the same time:

  • In Windows, Linux, and Chrome OS:
    • To zoom bigger: "Ctrl" and "+" keys
    • To zoom smaller: "Ctrl" and "-" keys
  • Mac OS:
    • To zoom bigger: "⌘" and "+" keys
    • To zoom smaller: "⌘" and "-" keys

Browsers provide specific guidance on different ways to change the page zoom or text-only zoom:

Other text and colour changes

Some browsers provide functionality to set different aspects of font and colour in the default view.

Other text and colour settings are available in Reader View.

Reader View

Most browsers offer a “Reader View” or “Reading View” that shows just the main content; it gets rid of navigation, ads, etc. Some browsers let you set the text font, text size, text colour, background colour, and line spacing in Reader View.
