Accessibility Tips

This section contains a list of accessibility tips that you should review. Please note that there are some aspects of page design that are important to accessibility but can not be tested automatically by Bobby. Some of these may appear below in the accessibility tips section.
  1. Encode list structures and list items properly

  2. Group related controls and label each group

  3. Furnish keyboard shortcuts for form elements

  4. Make sure that headings are nested properly

  5. Style sheets should be used to control layout and presentation wherever possible

  6. Make sure that text, image, and background colors contrast well and that color is not used as the sole means of conveying important information

  7. Use the ABBR and ACRONYM elements to denote abbreviations and acronyms

  8. Provide summaries for tables of data

  9. If you can't figure out any other way to make a page accessible, construct an alternate version of the page which is accessible

  10. Avoid ASCII art. Replace it with an image and alternative text

  11. Considered adding keyboard shortcuts to important links

  12. Make sure that document structure is supported by the proper use of structural elements

Download Time

The following three column table gives download time statistics for the images, applets, and objects on this page. The first column contains the URL of each item, the second column the item size in kilobytes, and the third column the approximate download time for each item when using a 28,800 baud modem. At the end of the report, an arbitrary delay of 0.5 seconds is added for each file to account for slow-downs caused by HTTP connection times.
