VO: This is module four, making vital background information accessible. This video is one in a series showing how to make an Excel worksheet, section 508 conformant.
VO: When adding content to a worksheet, vital information may be created as a watermark or placed in the header or footer.
VO: When doing this, the content cannot be accessed by assistive technology. Assistive technology does not automatically read information in headers, footers, and watermarks.
VO: So you need to duplicate any vital information in cell A1. Look for vital information in headers, footers, and watermarks.
VO: For example, respond by x state, confidential, or do not distribute. Note, watermarks in Excel are floating objects and cannot be made accessible.
VO: Is the vital information duplicated in the first cell of the worksheet? If not, the document fails this test.
VO: This example includes vital information in the header that is not duplicated in the first cell of the worksheet.
VO: This example is not accessible because this vital information is not included in the reading order.
