是< q>标签与在html中手动添加双引号相同？ [英] Is the <q> tag same as adding double quotes manually in html?

问题描述

我最近开始从w3schools.com学习html。在这个例子中，我们可以使用<$添加双引号到任何文本c $ c>< q> >标签。我想知道的是，我们也可以手动添加双引号，例如

< q>文本引用< / q>

$ b

如果我们手动添加双引号，它们的渲染效果也会一样

text quoted

• 这两种方法有什么不同双引号？

解决方案

使用< q> 元素，阅读该页面的软件（浏览器，搜索引擎蜘蛛等）知道它是一个引号，可能对它有不同的处理规则：浏览器可能会以不同的方式呈现它，例如用斜体字或不同文化的引用符号（日本不使用引号，它们使用直角符号），搜索引擎可以在别处查找引用，提供引用。如果你不标记你的文本，那么这些场景都是不可能的。

这个属于语义网络的总称 - 它是关于标记通过描述其内容的含义，而不仅仅是它看起来的样子。

另外，不要使用W3Schools：它们在教授只需要达到和结束所需的绝对基本知识方面的声誉很差 - 目标往往与讨厌的捷径，它灌输坏习惯。相反，当我了解网络时，我会推荐诸如Mozilla Developer Network（MDN）之类的资源。

I have recently started learning html from w3schools.com. In this example we can add double quotes to any text by using <q> tag around it. What I wonder is that we can simply add double quotes manually too, e.g.

<q>text quoted</q>

will render just same if we instead add double quotes manually

"text quoted"

• Is there any differnce between these two methods to add double quotes?

解决方案

The difference is that when you use the <q> element the software reading the page (a browser, a search engine spider, etc) knows that it's a quotation and might have different processing rules for it: browsers might render it differently, in italics for example, or a different culture's quote symbols (Japan doesn't use quotes, they use right-angle symbols) and search engines could look-up the quote elsewhere and provide a citation. If you don't mark-up your text then none of these scenarios are possible.

This falls under the umbrella term "the semantic web" - it's about markup throughly describing its content's meaning, not just the way it looks.

Also, don't use W3Schools: they have a poor reputation for teaching only the absolute basics required to achieve and end-goal, often with nasty shortcuts and it instills bad habits. Instead I recommend resources like Mozilla Developer Network (MDN) when learning about the web.
