Applies to all technologies
This technique relates to:
The objective of this technique is to provide a long description without requiring the user to jump off to another location for the description. It also allows all users to see the description which may be useful to anyone who might miss some features in the non-text content.
With this technique, the long description is provided as part of the standard presentation (i.e. everyone receives it). The description is located near the non-text content but does not have to be the very next item. For example, there may be a caption under a chart with the long description provided in the following paragraph.
The location of this long description is then provided within the short text alternative so the user knows where to look for it if they cannot view the non-text content.
There is a bar chart on a Web page showing the sales for the top three salespeople.
The short text alternative says: "October sales chart for top three salespeople. Details in text following the chart:"
The following is in the paragraph immediately below the chart. " Sales for October show Mary leading with 400 units. Mike follows closely with 389. Chris rounds out our top 3 with sales of 350"
