Items sorted by priority

This section presents all items found for the pages tested. Items are grouped by the three priority levels assigned by the W3C: Priority 1 (high), Priority 2 (moderate), and Priority 3 (low). It may be most practical to address items in that order in so you can achieve baseline access as quickly as possible. Note that some items are not fully detectable by Bobby and may not be issues on your site; follow the link for each item for more information.

[Priority 1 (high)] If a table has two or more rows or columns that serve as headers, use structural markup to identify their hierarchy and relationship.
[Priority 1 (high)] If an image conveys important information beyond what is its alternative text, provide an extended description.
[Priority 1 (high)] Provide alternative content for each SCRIPT that conveys important information or functionality.
[Priority 1 (high)] For tables not used for layout (for example, a spreadsheet), identify headers for the table rows and columns.
[Priority 1 (high)] If you use color to convey information, make sure the information is also represented another way.

[Priority 2 (moderate)] Avoid use of deprecated language features if possible.
