Meta
There are two types of attributes: Name and HTTP-equiv.
The name attribute is mainly used to describe a webpage, corresponding to content (webpage content ), this allows search engines to search for and classify robots. (currently, almost all search engines use online robots to automatically search for Meta values to classify webpages ). The most important of these are description and keywords. Therefore, you should add a meta value to each page.

5. <meta name = "Robots"
Contect = "All | none | index | noindex | follow | nofollow">
The attributes are described as follows:
Set to all: the file will be retrieved, and the link on the page can be queried;
Set to none: files will not be retrieved, and 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 retrieved, but the link on the page can be queried;

HTTP-equiv attributes
1. <Meta

2. <Meta
HTTP-equiv = "refresh" content = "N; url = http: // yourlink">

3. <meta http-equiv = "expires"
Contect = "mon, 12 May 2001 00:20:00
GMT "> it can be used to set the expiration time of a webpage. Once the webpage expires, it must be called again on the server. Note that the GMT time format must be used;
4. <Meta
HTTP-equiv = "Pragma"
Contect = "no-Cache"> it is used to disable the browser from accessing the page content from the cache of the Local Machine. Once set, it cannot be called out from the cache once it leaves the page;
5. <Meta
HTTP-equiv = "Set-cookie" contect = "mon, 12 May 2004 00:20:00
GMT "> cookie setting. If the webpage expires, the cookie on the disk will be deleted. Note that the GMT time format must be used;

8. <Meta
HTTP-equiv = "Page-Enter" contect = "revealtrans (duration = 10, Transtion =
50) "> and <meta http-equiv =" Page-Exit"

The duration value is the dynamic transition time of the webpage, in seconds.
Transition is a transitional mode. Its value ranges from 0 to 23, corresponding to 24 transition modes respectively. See the following table:
0
Box contraction 1 box radiation
2 circular contraction 3 circular radiation
4 From bottom up 5 from top down
6 from left to right 7 from right to left
8 vertical blinds 9
Horizontal blinds
10 horizontal blinds 11 vertical blinds
12 dissolve at will 13 expand from left and right ends to the middle
14 expand from the center to the left and right sides
