<meta> Label
Definitions and usage
<meta> elements provide meta information about the page (meta-information), such as descriptions and keywords for search engines and update frequencies.
The <meta> label is located on the head of the document and contains no content. The <meta> label properties define the name/value pairs associated with the document.
Differences between HTML 4.01 and HTML 5
The scheme attribute is no longer supported in HTML 5.
In HTML 5, there is a new CharSet property that makes the definition of a character set easier.
In HTML 4.01, you have to write this:
<meta http-equiv= "Content-type" content= "HTML; Charset=iso-8859-1 ">
In HTML 5, that's enough:
<meta charset= "Iso-8859-1" >
