HTML and CSS Reference
In the next section, you'll learn about some of the new elements that
have been added to HTML5 as a result of this research.
New elements for page structure
By page structure we mean the top-level items: the header, the footer, the
navigation, the main content, and so on. Let's join A.J. and Greg, who
are discussing the research results from the previous section.
It's common for web pages to have many distinct sections. A blog
homepage usually has several blog posts, each a section in itself, and
each blog post may have a comments section or a related-posts section.
HTML4 offers only one type of element for this common need: <div> .
HTML5 adds two new elements: <section> and <article> .
