Question

I typically use divs to nest my elements.

However, Dustin Diaz mentioned using the fieldset in this article.

When do you use fieldset instead of divs, and how does it help?

Answer 1

fieldset has semantic meaning, to hold form elements. A div does not have this meaning.

Also, by default, browsers can render it more suited as a form – i.e. when you use the legend child of fieldset, you can get a title for your fieldset rendered by the browser for you.
