Although section elements are technically styleable, we still recommend using div elements when there are complex styles or scripts.

Similar to the

element, the section element is used to list content.

So in a real example, the reason for using the

element is to structure the content of the blog. The code is as follows:

<div class="blog">   
    <section class="post">   
        <h2 class="post-title">Blog Post Title</h2>   
        <p class="post-excerpt">Ice cream tart powder jelly-o.    
        Gummies chocolate cake ice cream cookie halvah tiramisu jelly-o.</p>   
    </section>   
    <section class="post">   
        <h2 class="post-title">Blog Post Title</h2>   
        <p class="post-excerpt">Ice cream tart powder jelly-o.    
        Gummies chocolate cake ice cream cookie halvah tiramisu jelly-o.</p>   
    </section>   
    <section class="post">   
        <h2 class="post-title">Blog Post Title</h2>   
        <p class="post-excerpt">Ice cream tart powder jelly-o.    
        Gummies chocolate cake ice cream cookie halvah tiramisu jelly-o.</p>   
    </section>

【Elements have something to say】

section：

Hello, ladies and gentlemen, I am section. The international conference I attended introduced me like this, "The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading." I am with Semantic div, "Examples of sections would be chapters, the various tabbed pages in a tabbed dialog box, or the numbered sections of a thesis. A Web site's home page could be split into sections for an introduction, news items, and contact information ." The scenes I attend are usually chapters with articles, tabs in a tab dialog box, or numbered sections of a paper. A website's homepage can be divided into sections such as introduction, news, and contact information. I'm not just an ordinary container tag. When a tag is just for styling or to facilitate scripting, you should go to my friend div . Generally speaking, I'm good with elements when their content clearly appears in the document outline. Usually with a heading,

. I would use it to chunk content on pages in a website or application.
