The content of this article is about what is the head tag? The introduction of the head tag in HTML has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
The head tag is the content of the
element. Unlike the content of the element, which can be displayed in the browser, the content of the head will not be displayed in the browser. Its function is to contain some metadata of the page. In the example below, head has very little content.<head> <meta charset="utf-8"> <title>My test page</title> </head>
Metadata is the data that describes the data.
The element
Metadata describes the data data, and HTML has an "official" way to add metadata to a document - the element. Of course, the other things mentioned in this article can also be considered metadata. There are many different kinds of elements that can be included in the
element of your page, but we won't try to explain all of them just yet, as that would just cause confusion.<meta charset="utf-8">
This element simply specifies the document's character encoding - the character set that is allowed to be used in this document. utf-8
is a universal character set that contains most characters in any human language. This means that your web pages can be displayed in any language; many
elements contain name and content attributes. The
name attribute specifies the type of meta element; Describes what type of information this element contains.
content specifies the actual metadata content.
These two meta elements are useful for defining the author of your page and providing a description of the page's content.
<meta name="author" content="Chris Mills"> <meta name="description" content="The MDN Learning Area aims to provide complete beginners to the Web with all they need to know to get started with developing web sites and applications.">
Specifying the author can be useful in certain situations: if you need to contact the author of a page to ask questions about the page's content.
Some content management systems can automatically obtain the page author's information and then use it for certain purposes.
It is useful to specify a description of the page content that contains keywords about the page content, because it may or may not make your page appear more in relevant searches in search engines (these actions are termed
Search Engine Optimization, or SEO.)
