< section>的区别是什么？和< div&gt ;? [英] What is the difference between <section> and <div>?

问题描述

HTML中的< section> 和< div> 有什么区别？我们是不是在两种情况下都定义了部分？

解决方案

< section> 表示内部的内容被分组（即与单个主题相关），并应该作为页面大纲中的条目出现。

<$ c $另一方面，除类 并不表示任何意义 c>， lang 和 title 属性。

no：使用< div> 不会定义HTML中的一段。

$ b $ h




$ b $ p> < section> 元素表示文档或应用程序的通用部分。在这方面，一节是内容的主题分组。应该标识每个部分，通常通过包括标题（h1-h6元素）作为< section> 元素。

章节的例子可以是章节，标签对话框中的各种标签页或者论文的编号部分。一个网站的主页可以分成几个部分介绍，新闻和联系信息。

...

< section> 元素不是通用的容器元素。当仅仅为了样式目的或为了方便脚本而需要元素时，鼓励作者改为使用< div> 元素。一般的规则是，只有元素的内容在文档的大纲中明确列出时，< section> 元素才是合适的。

< div>

< div> 元素根本没有特别的意义。它代表了它的孩子。它可以用于类， lang 和 title 属性来标记一组连续元素共有的语义。

注意：强烈建议作者查看< div> 元素作为最后一招的元素，因为当没有其他元素适合时。使用更合适的元素而不是< div> 元素可以更好地为读者提供可访问性，并且为作者提供更易于维护的功能。

What is the difference between <section> and <div> in HTML? Aren't we defining sections in both cases?

解决方案

<section> means that the content inside is grouped (i.e. relates to a single theme), and should appear as an entry in an outline of the page.

<div>, on the other hand, does not convey any meaning, aside from any found in its class, lang and title attributes.

So no: using a <div> does not define a section in HTML.

From the spec:

<section>

The <section> element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content. Each section should be identified, typically by including a heading (h1-h6 element) as a child of the <section> element.

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 <section> element is not a generic container element. When an element is needed only for styling purposes or as a convenience for scripting, authors are encouraged to use the <div> element instead. A general rule is that the <section> element is appropriate only if the element’s contents would be listed explicitly in the document’s outline.

<div>

The <div> element has no special meaning at all. It represents its children. It can be used with the class, lang, and title attributes to mark up semantics common to a group of consecutive elements.

Note: Authors are strongly encouraged to view the <div> element as an element of last resort, for when no other element is suitable. Use of more appropriate elements instead of the <div> element leads to better accessibility for readers and easier maintainability for authors.
