![]() The draft text applies table summary functionality universally, and in a such way that it is not possible to distinguish the summary from a caption.One of the techniques described above should be used instead. "The attribute on table elements was suggested in earlier versions of the language as a technique for providing explanatory text for complex tables for users of screen readers. Recommends against using Makes it an obsolete attribute.Discusses alternative mechanisms for providing a visible caption of the table.Some long term solutions have been offered for growth to better practice. On the other hand, the attribute has been in HTML since HTML 4, there are sites that use it correctly, and the WAI community has provided advice in support of inclusion. (Source: Significant Floods of the 20th Century)Ī survey of existing web content showed that this attribute was rarely used, and, when it was, it was frequently misused, leading to the conclusion that it should be removed from HTML 5. Providing summary information visually by default would be extra verbiage that most authors/designers would be reluctant to include visually on a page because of redundancy. A summary mechanism therefore provides a 'quick scan' feature for non-sighted users that requires no complex user interaction beyond giving the table element focus. These useful semantics, such as those supplied by are often the difference between "seeing" or "not seeing" the table as a whole. However for users with visual impairments, additional semantics are often needed as a vital aid to comprehension. A summary mechanism may seem irrelevant or redundant to those with good eyesight because they have access to content relationships at a glance. The mechanism needs to be explicitly associated with the table or it becomes more difficult for AT to make that association. This is because an AT user needs to easily form a mental image of a table's contents in order to better understand its structure, or semantic relationships. This feature provides an overview of tabular data or a brief explanation of how to navigate a data table for Blind/Non-Visual Users who use assistive technology (AT). HTML 5 lacks a nonvisual explicitly associated, programmatic mechanism to provide a table with a summary for users who are can not see the visual rendering of the table. In HTML 4 this often much needed information is provided via the summary attribute. ![]() Vision impaired screen reader users listen to outputted information, without any visual cues, and HTML 5 currently lacks a programmatically-determined mechanism that gives an overview of complex tabular data or a brief explanation of that data.

Members of our free online marketing community have limited access. It's good to keep in mind that you need a Moz Pro account to access most of the information gathered. When this happens, the user-agent, Dotbot, is used to identify our crawler. Some of our tools, like Link Explorer, require us to crawl websites. Dotbot is different from Rogerbot, which is our site audit crawler for Moz Pro Campaigns. This data we collect through Dotbot is available in the Links section of your Moz Pro campaign, Link Explorer, and the Moz Links API. Dotbot is Moz's web crawler, it gathers web data for the Moz Link Index.
