The big role of HTML meta
|
There are two meta attributes: name and http-equiv. The name attribute is mainly used to describe the web page, corresponding to the content (web page content), to facilitate search engine robots to find and classify (currently almost all search engines use online robots to automatically find meta values to classify web pages). The most important of these are description (description of the site on search engines) and keywords (category keywords), so a meta value should be added to each page. The more commonly used ones are the following: name attribute 1, <meta name="Generator" contect=""> is used to describe the generation tool (such as Microsoft FrontPage 4.0), etc. 2. <meta name="KEYWords" contect="">Inform search engines of the keywords of your web page; 3. <meta name="DEscription" contect="">Tell search engines the main content of your site; 4. <meta name="Author" contect="your name"> Tell search engines the author of your site; 5. <meta name="Robots" context="all|none|index|noindex|follow|nofollow"> The properties are described as follows: Set to all: files will be retrieved and links on the page can be queried; Set to none: the file will not be retrieved and the links on the page cannot be queried; Set to index: the file will be retrieved; Set to follow: links on the page can be queried; Set to noindex: the file will not be indexed, but the links on the page can be queried; Set to nofollow: The file will not be indexed, but the links on the page can be queried. http-equiv attribute 1, <meta http-equiv="Content-Type" contect="text/html";charset=gb_2312-80"> and <meta http-equiv="Content-Language" contect="zh-CN">to describe the text and language used to create the homepage; For example, English is ISO-8859-1 character set, and there are also BIG5, utf-8, shift-Jis, Euc, Koi8-2 and other character sets; 2. <meta http-equiv="Refresh" contect="n;url=http://yourlink">Schedule the web page to jump to the page http://yourlink within the specified time n; 3. <meta http-equiv="Expires" contect="Mon,12 May 2001 00:20:00 GMT"> can be used to set the expiration time of the web page. Once it expires, it must be called again on the server. It should be noted that the GMT time format must be used; 4. <meta http-equiv="Pragma" contect="no-cache"> is used to prohibit the browser from accessing the page content from the local machine's cache. Once it is set, once you leave the web page, it cannot be retrieved from the cache; 5. <meta http-equiv="set-cookie" contect="Mon,12 May 2001 00:20:00 GMT">Cookie settings. If the web page expires, the saved cookies will be deleted. It should be noted that the GMT time format must be used; 6. <meta http-equiv="Pics-label" context="">Web page rating. There is a content setting in IE's internet options that can prevent browsing of some restricted websites. The restriction level of the website is set through the meta attribute; 7. <meta http-equiv="windows-Target" contect="_top">Force the page to be displayed as an independent page in the current window, which can prevent your web page from being called as a frame page by others; 8. <meta http-equiv="Page-Enter" contect="revealTrans(duration=10,transtion= 50)"> and <meta http-equiv="Page-Exit" contect="revealTrans(duration=20，transtion=6)"> set special effects when entering and leaving the page. This function is the "Format/Web Page Transition" in FrontPage, but the added page cannot be a frame page. The above are some commonly used meta attributes. If you have a personal homepage, you might as well add it to your homepage. The effect will be different:). |
