The purpose of using “aria-labelledby” on already labeled input elements?

Hi everyone,

I have seen many ARIA tutorial websites use codes such as the following one:

> <label for="name" id="label-name">Your Name</label>
> <input  id="name" aria-labelledby="label-name" type="text">
>
>
Since the input element has already been labeled by the label element which
is using for attribute, I'm wondering what the purpose of using
aria-labelledby attribute is in the above case.

I'm pretty new to ARIA, so am hoping that someone could clear up my
confusion. Thanks in advance.


Kind Regards,
Ian Yang
