我不理解html中的doctype。
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
请你解释一下这里的含义是什么。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
!DOCTYPE - The document type declaration
HTML - The root element is HTML, the type of document is HTML
PUBLIC - Availability - this is a public doctype
"-//W3C//DTD HTML 4.01//EN" - A formal identifier
"http://www.w3.org/TR/html4/strict.dtd" - URI, here it is the location of the DTD
about.com还有进一步细分。

该doctype的部分是:
Root element: HTML
DTD type: PUBLIC
Formal Public Identifier: "-//W3C//DTD HTML 4.01//EN"
DTD URL: "http://www.w3.org/TR/html4/strict.dtd">
但是,你真的不必知道这一切意味着什么。只需从W3C's recommended list of doctype declarations中选择一个doctype声明。
