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.
