The section element represents a generic document or application section. A section,in this context,is a thematic grouping of content,typically with a heading,possibly with a footer.

Note: The section element is not a generic container element. When an element is needed for styling purposes or as a convenience for scripting,authors are encouraged to use the div element instead.

如果许多元素是主题相关的,并且可以在共同的标题(例如“鞋”)下分组在一起,则将产品包装在一个部分中.

如果您正在包装的元素不相关,则不能将其分组在一个通用标题下,并且正在被包装以便进行样式化,然后使用div.

为了完整,article标签代表(从同一页)：

a self-contained composition in a document,page,application,or site and that is,in principle,independently distributable or reusable,e.g. in syndication. This could be a forum post,a magazine or newspaper article,a blog entry,a user-submitted comment,an interactive widget or gadget,or any other independent item of content.

所以您的销售项目将分别是该部分中的一篇文章.

作为最后一个注意事项,我不会将整个页面包含在< div role =“main”&gt ;:中：标题位于主要内容之外.
