name attribute and content attribute

## The #name attribute is used to describe a web page. It is a name in the form of "name/value". The content (value) described by the value of the name attribute is represented by the content attribute, which is convenient for search engine robots to find and classify. The most important of them are description, keywords and robots.

http-equiv attribute and content attribute

The http-equiv attribute is used to provide the response header message of the HTTP protocol, which starts with " A name in the form of "name/value". The content (value) described by the value of the http-equiv attribute is represented by the content attribute, which is usually provided to browsers and other devices before the web page is loaded. The most important of them is that content-type charset provides encoding information, refresh refreshes and jumps pages, no-cache page cache, and expires web page cache expiration time.
