Changing page magnification

You can change the magnification (zoom) of any page using your web browser. This will enlarge all elements of the page equally, images as well as text.

In recent versions of browsers for Windows, pressing the Control key plus the + key (on the main keyboard, not the number pad) will magnify the page and the Control key plus the - key will make it smaller. To return to the default size, press the Control key plus 0 (the figure zero). An alternative is to hold down the Control key and rotate your mouse’s scroll wheel to change the level of zoom.

Other methods for various browsers:

• In Internet Explorer, Firefox and Google Chrome, go to the menu and select View followed by Zoom (If the menu isn’t visible, press the Alt key to make it appear. On the keyboard, select Alt + V followed by Alt + Z). Choose the image size you require.
• In Opera, you need only press the plus or minus keys (+ or -) to change page magnification.
• With Safari on Apple computers, hold down the Command key (the Apple key) and select the plus key (+) to increase the text size or the minus key (-) to decrease it.

Standards compliance

Most pages comply with Level AAA of the 2.0 revision of the Web Content Accessibility Guidelines (WCAG), the remainder to Level AA.

Pages validate as HTML5 and use valid Cascading Style Sheets (CSS3) as determined by the W3C Validation Services. If you turn CSS off the content will still be readable. Page structures match the needs of screen readers.

Versions of Internet Explorer before 9.0 are obsolete and aren’t supported; they won’t render pages as intended.
