On many bootstart sites, I see the following code to insert an icon:

& lt; i class = "glyphicon glyphicon-plus" aria-hidden = "true" & gt; & lt; / i & gt;

Why is this aria-hidden hint needed?

Is this a good practice, or is it bad or wrong?

I usually don’t like to paste in code that I don’t understand, so I clear out aria-hidden . But maybe I’m wrong and it’s time to deal with this issue.

I looked for information on the net, but what I found was even more confusing.

It seems that this tag somehow helps visually impaired users navigate the page, but how exactly – I do not understand.

Please help clarify the issue.

Generally the aria attributes are needed for people with disabilities as well as for reading mode. In your case, aria-hidden means that the element is optional to show. The practice is undeniably good.
