What is ARIA attribute?

Accessible Rich Internet Applications (ARIA) is a set of attributes that define ways to make web content and web applications (especially those developed with JavaScript) more accessible to people with disabilities.

It supplements HTML so that interactions and widgets commonly used in applications can be passed to assistive technologies when there is not otherwise a mechanism. For example, ARIA enables accessible navigation landmarks in HTML4, JavaScript widgets, form hints and error messages, live content updates, and more. ARIA was invented after HTML4, so does not validate in HTML4 or its XHTML variants.

What ARIA attributes to use on HTML elements?

aria-label: aria-label is used to add a label with any input field or CTA that will be identified by screen reader devices. This is helpful when we have any such form field that doesn't have a label and we are using a placeholder to describe the field. e.g. aria-label="Submit the application form"

aria-describedby

aria-required

aria-invalid

aria-hidden

aria-expended: aria-expended attribute is used with accordion where we set expended value true or false. When an accordion is open to read then set aria-expended="true" attribute otherwise aria-expended="false". 

Hope this ARIA article helps you to apply accessibility to your website and makes your site or portal accessible for all users.

Can we change the production release time set in cloud manager?

 Yes, we can change the production release or scheduled release time in the cloud manager pipeline. At the step of schedule production deployment, we will see the option to Change the schedule, from there we can reschedule the deployment time.

Schedule Production Deployment Step in Adobe Cloud Manager 

Note: we will try to change or schedule the production release within 2 hours then this option will not allow you to do so and an error message populates "Please make sure the selected date and time is between 2 and 72 hours in the future". In that case, use the Schedule production deployment release now option and proceed with deployment.
