What is tag

In HTML, a tag tells the browser what to do. When you write an HTML page, you enter tags for many reasons -- to change the appearance of text, to show a graphic, or to make a link to another page.

Differences between XML and HTML

Since XML and HTML are derived from SGML they are similar, but have the following differences:
1. XML is case-sensitive
2. XML must have quotes (single or double) around attributes
3. Most interpreters of HTML are very forgiving about missing end tags - XML parses are not.
4. Comments start with <-- and end with -->. Inside a comment, "--" may not appear. Although this is fine in html, it confuses xml parsers.

CSS SYNTAX

A "doctype" or to give its full name "Document Type Declaration" (DTD) should be the first line of your HTML document, right before the opening <html> tag. No white space no comments no nothing else should appear before it.
