Recommended Meta Elements?
Setting up a "basic framework" for my website projects, I'm wondering which meta elements are really necessary/recommended? In particular, I'd like to know how to deal with the language attribute(s)!? In the following example, I think sth. is repeated unnecessarily...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" dir="ltr">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta http-equiv="content-style-type" content="text/css" />
<meta http-equiv="content-script-type" content="text/javascript" />
<meta http-equiv="content-language" content="en" />
<meta http-equiv="language" content="en" />
<title> Title </title>
<base href="http://www.mydomain.com" />
<meta name="charset" content="utf-8" />
<meta name="content-language" content="en" />
<meta name="language" content="en" />
<meta name="description" content="description" 开发者_开发问答/>
<meta name="keywords" content="keywords" />
</head>
P.S. "content-language" = "language"?
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
Definitely recommended
<meta http-equiv="content-style-type" content="text/css" />
Useless, browsers only support CSS.
<meta http-equiv="content-script-type" content="text/javascript" />
Useless, browsers only support JavaScript.
<meta http-equiv="content-language" content="en" />
Redundant to <html lang="en">
<meta http-equiv="language" content="en" />
Doesn't exist, AFAIK.
<title> Title </title>
Definitely recommended.
<base href="http://www.mydomain.com" />
Depends on how you want your relative links to work, I suppose.
<meta name="charset" content="utf-8" />
<meta name="content-language" content="en" />
<meta name="language" content="en" />
Look like typo's.
<meta name="description" content="description" />
Probably useful.
<meta name="keywords" content="keywords" />
Ignored by every search engine due to widespread abuse.
Use this for HTML 5:
<!DOCTYPE html>
This looks wrong:
<meta name="charset" content="utf-8" />
should probably be this for HTML 5:
<meta charset="utf-8">
That is the new HTML 5-way of setting charset encoding. It is highly recommended to also include the old way:
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
These should be directly after the opening head-tag:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title>The title</title>
</head>
<body>
</body>
</html>
加载中,请稍侯......
