Q How do you decide when to start using HTML5 structural tags?

A If you’re creating web pages for an audience that uses known browsers, you can
use whichever tags those browsers support. For example, at my job, all of the
employees use Google Chrome, so we can use HTML5 tags whenever we’re work-
ing on internal applications. However, on our public website, we continue to need
to support browsers that do not yet provide HTML5 support. Furthermore, we have
a large web application that was written before HTML5 existed, so we would have
to change all of our pages to use the new tags. These days the majority of websites
are written in HTML5, and if you haven’t upgraded your site yet, you should be
considering it.

Quiz Answers

1. In HTML4, the page outline is defined based on the headers used on the page.


2. Placing headings in a
   tag doesn’t change the heading behavior at all. It
   just gives the section a title for the outline.


3. This was a trick question. None of the new HTML5 structural elements affect the
   layout of the page.


4. The
   tag does not define a new page section.
