Coding standards and Double-A conformance

This website is built using code compliant with World Wide Web Consortium (W3C) standards for XHTML and Cascading Style Sheets. W3C is the governing authority on web development standards and practices.
The site displays correctly with current browsers, and using standard XHTML code means that any future browsers will also display this website correctly.
We are continuously improving this website to ensure that pages conform to the Double-A level of the W3C Web Content Accessibility Guidelines 1.0.
The Accessibility Guidelines explain how to make Web content accessible to people with disabilities. Conformance to these Guidelines helps to make the Web more accessible to users with disabilities and benefits all users.
There may be a few pages that do not conform to all the guidelines. Whilst every effort is made to ensure the whole site conforms, with many web contributors, this is an ongoing process.

Images and alt tags

Where images are used we have added 'Alt' tags - text alternatives so that you will still know what the image is meant to convey even if it doesn't load or if you've have chosen to browse with the images switched off or you are using an assistive technology like a screen reader to browse the web page rather than view.

Resizable text

We have been careful to make sure that we haven't fixed the size of the textual information on the website so that visitors who wish to can alter the font size on the screen to make it easier to read.
There are a number of ways to change the text size in your browser, the easiest way is to follow the steps below (Internet Explorer and Firefox):

  • Select the 'View' menu.
  • Select the 'Text Size' option from the menu.
  • Click on the text size you wish to view.

It is also possible to increase the size of the text by holding down the Ctrl key on the bottom left hand row of the keyboard whilst using the scroll wheel on your mouse to increase (or decrease) the size of the text.
If you don't have a scroll wheel, you can also hold down Ctrl and hit the + (plus) key to increase text size, or the - (minus) key to decrease text size.

Colours and contrast

We have considered the needs of users who are colourblind by selecting colour combinations with sufficient contrast between foreground and background.
You can however use your own preferred colour scheme - check your internet browser's Help section for details.
