Breaking the rhubarb example into pieces
Step 1: Main content
What is the main content of the page? What comes before and what comes after?
Our first division of our example is into three elements, namely a header element, a main element, and a footer element.

Main, header, and footer
Step 2: Articles and sections
Can the main content be broken into self-contained articles? Are there groups of articles that belong in the same section?

Sections
In the example, we have split the information into two section elements. The first section contains articles about general information (Stalking rhubarb, How to identify rhubarb, Washing rhubarb, Fun facts about rhubarb, and Not-so-fun facts about rhubarb) and the second section contains articles with recipes (Ginger rhubarb ice milk and No-ginger rhubarb ice milk).

Articles
Step 3: Other features
Are there any figures? Are there hyperlinks for navigation? Is there any information that is tangential to the main content?

Other features
In our example, we have a figure consisting of an image and a caption and also a list of hyperlinks to related sites. Since the list of hyperlinks is tangential, we have put it in an aside element.
