Accessibility Tips

Text size and colour

Q: Can I change font sizes and the colours of the website?

A: Yes. This may be useful for you if you have low vision, and need larger fonts or high contrast colours. You can change the font size, style and colour, and choose an alternative colour for links. You can also change background and foreground colours.

Q: How do I do that on a PC?

A: If using Internet Explorer on a PC, select the View menu at the top of your window. To change font size, scroll down and select the Text size option. To ignore font and background colours choose the Internet options from the Tools menu at the top of the window. On the general tab of the window that appears, click the Accessibility button. This takes you to a menu where you can choose to ignore the way the page is formatted. Then return to the Internet options menu, and use the Colours and Fonts buttons to set your preferences.

Q: How do I do change text size on an Apple Mac?

A: From Internet Explorer, select Preferences from the Edit menu at the top of the window. From there, click on Web content and uncheck the Show style sheets option. Then return to the list of preferences and choose Web browser. Then click on Language/fonts and choose the size you need.
