HTML and CSS Reference
In-Depth Information
Notes
• The
html
element is the first element in a document. Except for comments, the only
tags it directly contains are
<head>
followed by either
<body>
or
<frameset>
.
• Because it is the outermost tag in a document, the
html
element is called the root
element.
• The
<html>
tag and its closing tag
</html>
are both mandatory under XHTML.
Under other specifications, including HTML5, the element is actually optional
because it is implied unless a comment is found as the first item within the
document.
<i> (Italic)
This element indicates that the enclosed text should be displayed in an italic typeface.
