What are these attributes: `aria-labelledby` and `aria-hidden`

Question

Using Bootstrap modal, I\'ve seen these aria attributes a lot, but I never knew how to make use of them.

Does anyone know what cases to use these attri

Answer 1

aria-hidden="true" will hide decorative items like glyphicon icons from screen readers, which doesn't have meaningful pronunciation so as not to cause confusions. It's a nice thing do as matter of good practice.
