Does HTML really mean this...

1. span and Div

Most labels have their meanings (semantics), such as P, paragraph, and H1. With the exception of span and DIV, but with the specific meaning given by the ID and class attributes, span and Div can be used to organize large HTML blocks.Code.

Span is an inline element. (Inline element)

DIV is a block element. (block element)

2. Meta of meta tags and Search Engine Optimization

<Meta name = "XX" content = "yyy"/>

XX can be author, keywords, description

<Meta http-equiv = "XX" conent = "yyy"/>

XX can beContent-Type(Type ),Expires(Timeliness ),Refresh(Refresh, how long the page will be automatically refreshed) andSet-Cookie(Set cookie)

HTTP-equiv will generate an HTTP data header, and the header information will be sent to the server.

U-underline. Non-link text with a fart underline...
