JQuery UI dialog: should I use h1, h2 or h3?

Question

Which HTML title tag (h1, h2, h3...) is supposed to be used in a JQuery UI dialog?

I know I can put anything and set the layout I want using CSS, but I would like to know if a title level is more appropriate than another one.

Answer 1

I would go for an <h3>, or at least and <h2>

<h1> is known to conceptually represent the main title of a page and is the top-level heading element anyway.

Note: despite the fact that the specification does allow it, it is generally accepted to not have multiple <h1> elements within the same page. Using it multiple times should be done carefully though.
