New windows

Links to non-Shell websites and downloadable files such as PDF, Zip, or Word open in a new browser window when clicked. This allows you to switch between the Shell website and the newly opened window. Links to non-Shell websites will first open a disclaimer statement, which will ask you to click on the ‘Continue your journey’ link to proceed. On all Shell websites, links that open in a new window are clearly marked either by text next to the link title or within the link title tag (alt text).

Page titles

Each page has its own unique page title that clearly explains the page content. This will help you keep track of where you are in the website, and make it possible to distinguish between pages when you have more than one window or tab open.


Headings are relevant and provided in a logical order so that you can use them to get an overview of the page. For screen reader users, this means that you may be able to use screen reader functions to jump from heading to heading, or have a list of all headings displayed, so that you can decide which one is of most interest to you, and then go straight to it.

Data tables

Data tables have row and column headings, where necessary, that are not only visually different from the data cells, but coded so that screen readers will be able to identify them. This will make it possible for screen reader users to find out what the relevant headings are, from anywhere within the table grid.


Links are written so that they are clear, concise, and unique on each page. This makes the links easier to scan visually as well as if you are using a screen reader.

Making text larger

A lot of web pages can be difficult to view because the text is too small to comfortably read. Choose from the following web browsers for step-by-step instructions on how to increase the size of the text on any web page you are viewing:

Internet Explorer (5.0, 5.5  6.0 7.0)
1. Open your Internet Explorer browser.
2. Open the ‘View’ menu with the mouse.
3. Click on ‘Text Size’.
4. Choose your preferred text size with the mouse, or use the up and down arrow keys and press 'Enter'.

Firefox (1.0, 1.5, 2.0)
1. Open your Firefox browser.
2. Open the ‘View’ menu.
3. Click on ‘Text Size’.

Magnifying your screen

If increasing the text size via the browser or Windows options does not make text easy to read another solution is to magnify your screen. All recent versions of Windows include magnification software, which can make it easier to read text on the screen.

The Windows magnifier lets you increase text to a very large size. It is, however, restricted to a small portion of the screen so most visually impaired people find that they require fully-functional magnification software.

  • Viewing problems

If you connect to the internet via a company network, a firewall may be preventing you from viewing video. Ask your IT department whether the firewall is configured to support streaming video and to check the proxy settings for your network. Windows Media Player loads a buffer to improve video quality. This usually takes about 30 seconds. Once the buffer is loaded, the video should start playing.

  • Sound problems

If you can see the video but you cannot hear it, check:

a) if your speakers are switched on

b) the volume settings in Windows Media Player

c) your sound card settings.

If you are able to receive audio, but the sound quality is poor, adjust your speaker volume and adjust the volume settings in Windows Media Player.
