Accessible Tables

There is no question that the vast majority of tables on the Web are layout tables, used to structure the visual appearance of the page. Often the structure of tables is remarkably complex, with tables nested in tables as much as seven deep.

Can the alt Attribute Be Omitted Without Hurting Accessibility?

In the current editor’s draft of the HTML 5 specification, the alt attribute for images is no longer required. I am not convinced that this is a good idea.

HTML 5, Microformats and Testing Accessibility

Testing is vital, particularly at the border of accessibility theory and practice. I wonder, for example, if tabindex and accesskey would have made it to the HTML4 spec if there had been full testing with assistive technology users? What I really want to know from the HTML5 people is who they think is going to do this research that will provide the evidence that their gang requires before useful attributes are restored to the specification.

HTML 5 and the Summary Attribute

As I wrote in Help screen reader users by giving data tables a summary, the summary attribute on the table element can be used to provide information that helps non-sighted users understand data tables. The current draft of HTML 5 requires that validators display a warning if they encounter a summary attribute, since it is now an 'obsolete but conforming feature.'
