Web Front-endH5 TutorialHTML5 study notes concise version (2): new elements section, article, aside
section
The section element describes a common section in a document or program. Generally speaking, a section contains a head and a content content block. A section can be represented as a section, or a box block under a tab on a tab page. A page can be split into multiple sections, representing introduction, news items and contact information respectively.
If the content of the element can be displayed together to express the corresponding meaning, it can be defined as an article element, and there is no need to use the section element.
The section element is not a general container element, so if an element needs to define a corresponding style or script, it is recommended to use the div element. The condition for using section is to ensure that the content of this element can be clearly displayed in the document. in the outline.
The following example code comes from part of the Apple website page. The code contains 2 short sections:
<article>
<hgroup>
<h1 id="Apples">Apples</h1>
<h2 id="Tasty-nbsp-delicious-nbsp-fruit">Tasty, delicious fruit!</h2>
</hgroup>
<p>The apple is the pomaceous fruit of the apple tree.</p>
<section>
<h1 id="Red-nbsp-Delicious">Red Delicious</h1>
<p>These bright red apples are the most common found in many supermarkets.</p>
</section>
<section>
<h1 id="Granny-nbsp-Smith">Granny Smith</h1>
<p>These juicy, green apples make a great filling for apple pies.</p>
</section>
</article>As you can see, you can use the h1 element arbitrarily in the section without considering it. This section is a top-level, second-level or third-level element.

</section>
</body>
</html>article
Article represents an independent fragment of the content of a document, for example, a blog entry or a newspaper article. The content of the
article is a special section tag, which has clearer semantics than section. It represents an independent and complete block of related content. Generally, an article will have a title section (usually contained within the header) and sometimes a footer. Although a section is also a thematic piece of content, the article itself is independent and complete in terms of structure and content.
When article is embedded in article, in principle, the content of the inner article is related to the content of the outer article. For example, in a blog post, the article containing user-submitted comments should be hidden within the containing blog post article.
<article> <a href="http://www.apple.com">Safari 5 released</a><br /> 7 Jun 2010. Just after the announcement of the new iPhone 4 at WWDC, Apple announced the release of Safari 5 for Windows and Mac...... </article>
