As we explained in the previous chapter, the header element contains summary information about the document.
The HTML also contains a META element that is inside the head element. The role of the META element is to provide meta-information about the document.
In most cases, meta elements are used to provide information about a browser or search engine, such as describing the contents of a document, and so on.
Note: "Some user programs support using META to refresh the current page and replace it with another URL in a few seconds," the statement said. Developers should not use this technique to force users to go to different pages, as this will make the usability of the page worse. Instead, use server end multiplicity orientation for automatic page orientation.
See: Http://www.w3.org/TR/html4/struct/global.html#adef-http-equiv.
Keywords for search enginesSome World Wide Web search engines use the name and content properties of the META tag to index pages.
This Meta element defines the description of the page:
<name= "description" content= "Free Web tutorials on HTML, CSS, XML, and XHTML "/>
This Meta element defines the keywords for the page:
<name= "keywords" content= "HTML, DHTML, CSS, XML, XHTML, JavaScript, VBScript ">
The role of the name and content properties is to describe the content of the page.
However, because a lot of network managers use META tags to create spam, such as repeating keywords on the page to achieve the goal of improving rankings, some search engines have completely abandoned the use of them.
Please read our website building tutorials to learn more about search engines.
Unfamiliar meta-attributesSometimes you will find some meta attributes that are unfamiliar to you, such as:
<name= "Security" content= "Low">
You just have to understand that these things have some special meaning for the site or developer, and maybe it doesn't matter to you.
You can also find more information about meta tags in our complete HTML4.01 label reference Manual.
