What’s probably coming in the ARIA1.2?_part2

A Quick recap

This is the continuation of part1(what’s probably going to come in ARIA1.2-part1) blog post and we pretty much covered the new roles(such as blockquote, caption, code, deletion, insertion, and so on..)  that are probably going to come in the ARIA1.2 as part of the previous blog post. Let us look into the changes that are probably going to take place on the existing attributes and roles usage in this part2 blog post.

 

Changes that are probably going to take place on the existing roles and attributes usage

Combobox(role)

There are significant changes that are going to take place for combobox role(role=”combobox”)  in ARIA 1.2. ARIA 1.1 combobox role implementation pattern is going to be no longer valid once ARIA 1.2 becomes W3C recommendation as the support of ARIA 1.1 combobox role implementation pattern is not very great. ARIA 1.2 combobox implementation pattern talks more or less ARIA 1.0 combobox implementation with aria-controls instead of aria-owns.

 

Aria-disabled(state)

Aria-disabled attribute is not going to be global attribute any more and it is allowed only in the certain roles

 

Aria-invalid(state)

Aria-invalid attribute is not going to be global attribute anymore and it is allowed only in the certain roles. The value of aria-invalid is also going to be enumerated type and it means that aria-invalid accepts certain list of token values

Aria-errormesage attribute is not going to be global attribute anymore and it is allowed only in the certain roles.

Aria-haspopup attribute is not going to be global attribute anymore and it is allowed only in the certain roles.

 

Aria-expanded(state)

There are significant changes to aria-expanded attribute in terms of which role should allow and which role should not. Aria-expanded attribute is going to be allowed in the menuitem role, checkbox role and application role. In addition, aria-expanded attribute is not going to be allowed on many roles(such as alert, alert dialog, article, main, banner, contentinfo, and so on.)

 

Listbox(role)

Do you have a feedback on these proposed changes?

ARIA WG opened ARIA 1.2 for the public review around couple of months ago and feedback can be submitted in the W3C ARIA GitHub repository or can be emailed to public-aria@w3.org. ARIA 1.2 is probably going to be come candidate recommendation(CR) in a month or so. Later this year, hoping that it is going to be become W3C recommendation too

What’s probably coming in the ARIA 1.2?_part1

Overview

ARIA 1.2 main goal is to add certain new roles and update the existing attributes and roles usage based on the feedback that ARIA WG received. In addition, New terminologies like prohibited states and prohibited properties have been introduced. Prohibited states and prohibited properties are nothing but those attributes are not allowed for the certain roles. To give an example, paragraph role(which is new role in the ARIA 1.2) does not allow aria-label and aria-labelledby attributes and this means that authors must not use aria-label and aria-labelledby role on the paragraph role. ARIA 1.2 specification is currently in the draft stage and This means that ARIA 1.2 specification may subject to change based on the feedback. ARIA WG opened ARIA 1.2 for the public review around couple of months ago and feedback can be submitted in the W3C ARIA GitHub repository or can be emailed to public-aria@w3.org. ARIA 1.2 is probably going to be come candidate recommendation(CR) in a month or so. Later this year, hoping that it is going to be become W3C recommendation too. A big kudos to ARIA working group for working so hard for the evolution of ARIA and making the web better place for everyone!
