3. HTML vs. XHTML
HyperText Markup Language
HTML is the language that has
historically been used to
create documents on the web.
It is plain text, but includes a
variety of tags that define the
structure of the
document, and allow
documents to include
headings, paragraphs, images,
links, lists, tables, and other
features.
XHTML is a rewrite of HTML
as an XML language.
XHTML is very similar to HTML,
but has stricter rules. HTML
was relaxed about things such
as case sensitivity (XHTML
elements must be in lower
case) and closing tags (all
XHTML elements must be
closed).
4. CSS
Cascading Style Sheets
CSS is a language that is used in conjunction with HTML
to control how web pages are displayed. The difference
between HTML and CSS is that HTML defines the
structure and content of the document, and CSS
controls the presentation.
6. Precoding HTML Tags
<head>
Web pages are divided into two main sections:
the head and the body. The head provides information
about the document, including the author, description,
keywords, title, and other information.
*In our "bare bones" document the only content in the head
section of our web page is the title.
</head>
This marks the closing of the head section.
7. Precoding HTML Tags
<title>
You must give your document a title. This title
doesn't actually appear within the web page, but
appears in the title bar of the browser window.
This is also the title of the page that will be
displayed by default in search engine results or in
user's Favorites.
</title>
Closes the title tag.
8. Precoding HTML Tags
<body>
The body section contains the contents of your
document.
</body>
Closes the body tag.
</html>
Ends the html document.
