Accessibility
This is the official accessibility statement for EMP Masterclasses.
Although we've tested this site extensively there may be some aspect that doesn't work well, or could work better with your assistive technology. If so, please send your information and suggestions to accessibility.cambridge@tribalgroup.co.uk . We are constantly striving to provide users with the best viewing experience possible. Thanks!
Standards compliance summary
As far as possible, we have tried to ensure that:
- All pages on this site use CSS for layout and should degrade gracefully on non standards-compliant Web browsers.
- All style sheets conform to W3C recommendations.
- All pages on this site use structured semantic mark-up: h1 tags are used for main titles, h2 tags for subtitles, and so on.
- All pages comply with priority 1 guidelines of the W3C Web Content Accessibility Guidelines.
- All pages validate as XHTML 1.0 Transitional.
Text resizing
You can customise your browser (Internet Explorer, Mozilla, or similar programme) to make the text larger. If you are using Internet Explorer, choose View then Text Size and select Medium, Larger or Largest. Similarly in Netscape, choose View then Text Zoom.
Alternatively, some browsers allow you to change the text size using the keyboard:
'Ctrl' key and.
- - (for smaller)
- + (for larger)
- 0 (for default size).
Links
Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article). As far as possible, links are written to make sense out of context.
Images
1. All content images used in this site include descriptive alt tags. Purely decorative graphics include null alt tags or are displayed through the use of style sheets.
2. Complex images include 'longdesc' tags or inline descriptions to explain the significance of each image to non-visual readers.
Visual design
1. This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers.
2. If your browser or browsing device does not support style sheets at all, the content of each page should still be readable.
3. Information conveyed with colour is also available without colour for people who cannot differentiate between certain colours or who use devices that have non-colour or non-visual displays.
4. We have avoided content that causes the screen to flicker.
Other
- We have used the clearest and simplest language appropriate for a site's content.
- We have only used html tables to tabulate data and they have not been used to structure or lay out pages.
- We have ensured that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported.
- We will ensure that equivalents for dynamic content are updated when the dynamic content changes.
