Bobby Accessibility Summary Report
Bobby Approved status
These web pages do not meet the requirements for Bobby Approved status. Below is a list of 2 Priority 1 accessibility errors found:
- Provide alternative text for all images.
User checks
User checks are triggered by something specific on the page; however, you need to determine whether they apply. Bobby Approval requires that none of them apply to your site. Please review these 5 item(s):
- Be sure pages are readable and usable if style sheets are ignored.
- For tables not used for layout (for example, a spreadsheet), identify headers for the table rows and columns.
- If you use color to convey information, make sure the information is also represented another way.
- If an image conveys important information beyond what is its alternative text, provide an extended description.
- If a table has two or more rows or columns that serve as headers, use structural markup to identify their hierarchy and relationship.
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.
Items sorted by Ease to Fix
This section sorts items based on how easy it is to fix them. This is a subjective determination by CAST on these guidelines as a whole, not based on the analysis of your pages. Possible values are Easy, Moderate, or Hard.
