Can I use aria-Describedby?
The aria-describedby attribute is used to indicate the IDs of the elements that describe the object. This attribute can be used with any typical HTML form element; it is not limited to elements that have an ARIA role assigned.
What is the difference between aria-Labelledby and aria-Describedby?
The aria-labelledby attribute establishes the programmatic relationship between the widget element and the element providing the label. The aria-describedby attribute establishes a programmatic relationship between a widget element and the element with the descriptive information.
What is the use of aria-Labelledby?
The aria-labelledby attribute establishes relationships between objects and their label(s), and its value should be one or more element IDs, which refer to elements that have the text needed for labeling. List multiple element IDs in a space delimited fashion.
What is aria expanded true?
The aria-expanded attribute provides information about whether an element is in an expanded or collapsed state. For example, if you have a collapsible element which contains a text, then a screen reader would know that the text is not currently displayed on the screen when the aria-expanded attribute is set to true.
When do you use the ARIA describedby attribute?
The aria-describedby attribute is not used only for form elements; it is also used to associate static text with widgets, groups of elements, panes, regions that have a heading, definitions, and more. The Examples section below provides more information about how to use the attribute in these cases.
Can you add ARIA describedby to non focusable elements?
Both Firefox and Internet Explorer respect aria-describedby only in focus mode. As such, it does not make sense to add it to non-focusable elements. While NVDA announces descriptions right away, JAWS sometimes prompts to manually press JAWS + Alt + R to announce it.
Do you need to know how to use ARIA?
Easily ARIA can lead to significantly worse accessibility if not implemented and tested properly. Don’t use ARIA just to have some “cool things in the code” which you don’t fully understand.
Is the WAI-ARIA property compatible with other languages?
WAI-ARIA States and Properties is compatible with other languages as well; refer to documentation in those languages. The aria-describedby property is not designed to reference descriptions on an external resource — since it is an ID, it must reference an element in the same DOM document.
