Detailed explanation of HTML5 semantic markup Section and Article examples

Webpage production cnn6 article introduction: The most frequently asked question is: Under what circumstances should we use these elements? And how should we use these elements correctly?

HTML5 brings a series of new elements and will be widely used in the future. However, there are some elements that can be confusing to use, including two new elements:

and

.

The most commonly asked question is: under what circumstances should we use these elements? And how should we use these elements correctly?

Section element

This is the most ambiguous element. How is it different from the

element? We have been using

to divide paragraphs, so besides

, when do we use this element. We quote the official documentation to illustrate it. According to the WHATWG documentation, the

element is described as follows:

"The

element represents a common paragraph in a document or application - WHATWG"

From the description We can see that the function of the

element is to segment, more or less similar to

. But it still has a special case. In the document, a special statement was added:

"When an element is used solely for style or for script convenience, authors are encouraged to use

. The

element applies when When the content of an element needs to be explicitly listed. - WHATWG”

Based on this, we can summarize the following two points:

First, although the section element can technically be styled , but we still recommend using the p element when there are complex styles or scripts.

Second, 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:

<p 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>  
</p>

This is just an example, the

element Can also be used for other purposes.

Article element

From the name, it has already explained itself well, but we still have to look at how the official document describes it:

"In A document, page, application or section of a site that is, in general, independently redistributable or reusable, for example in a forum post, a magazine or news article, a blog entry, or a user submission. Comments, interactive widgets or widgets, or any other stand-alone item of content.”

From the above description, we can conclude that the

element is dedicated to structured articles, especially what we want. Published, such as blog, page content or forum posts.

The following example shows how to use

to build a blog article.

<article class="post">  
    <header>  
    <h1>This is Blog Post Title</h1>  
    <p class="post-meta">  
        <ul>  
            <li class="author">Author Name</li>  
            <li class="categories">Save in Categories</li>  
        </ul>  
    </p>  
    </header>  

    <p class="post-content">  
        Sweet roll halvah biscuit toffee liquorice tart pudding sesame snaps.   
        Biscuit powder jelly-o fruitcake faworki chocolate bar. Pudding oatnbon. Gummies   
        halvah gummies danish biscuit applicak   
        cake tootsie roll sesame snaps lollipop gingerbread boe gingerbread jelly-o pastry.  
    </p>  

</article>

In addition, the

element can also be combined with the section element. When necessary, the

element can be used to divide the article into several paragraphs, as shown in the following example.

<article class="post">  
    <header>  
    <h1>This is Blog Post Title</h1>  
    <p class="post-meta">  
        <ul>  
            <li class="author">Author Name</li>  
            <li class="categories">Save in Categories</li>  
        </ul>  
    </p>  
    </header>  

    <p class="post-content">  
        <section>  
        <h2>This is the Sub-Heading</h2>  
        Sweet roll halvah biscuit toffee liquorice tart pudding sesame snaps.   
        Biscuit powder jelly-o fruitcake faworki chocolate bar. Pudding oat cake   
        tootsie roll sesame snaps lollipop gingerbread bonbon. Gummies halvah   
        gummies danish biscuit applicake gingerbread jelly-o pastry.  
        </section>  

        <section>  
        <h3>This is another Sub-Heading</h3>

        toffee sesame snaps tart topping chupa chups apple pie gummies. Wafer chocolate  
        cake. Sugar plum chocolate bar topping ice cream carrot cake danish bonbon.   
        Cheesecake gummi bears dragée jujubes dragée dragée brownie jelly biscuit. 
        Powder croissant jelly beans pastry.  
        </section>  
    </p>  

</article>

Summary

As predicted by the founders of the World Wide Web and the directors of the W3C, all the new elements created by HTML5 are intended to make the web structure more semantic. The correct application of these elements is still a matter of debate among web developers and designers.

In any case, don’t mix up the ideas. As I mentioned before, if it makes sense and you see the structure making sense using it, then use it.
