Figure 1-2. An HTML5 page with all the new semantic markup elements
CHAPTER 1 ■ OVERVIEW OF HTML5
One last thing to keep in mind is that browsers may seem to render things as if they actually
understand these new elements. The truth is, however, that these elements could have been renamed
foo and bar and then styled, and they would have been rendered the same way (but of course, they
would not have any benefits in search engine optimization). The one exception to this is Internet
Explorer, which requires that elements be part of the DOM. So, if you want to see these elements in IE,
you must programmatically insert them into the DOM and display them as block elements.
Simplifying Selection Using the Selectors API
Along with the new semantic elements, HTML5 also introduces new simple ways to find elements in
your page DOM. Table 1-3 shows the previous versions of the document object allowed developers to
make a few calls to find specific elements in the page.
