Nigel Chapman and Jenny Chapman, Web Design: A Complete Introduction (John Wiley & Sons: 2006)

Our Web design text concentrates on Web standard technologies (HTTP, XHTML, CSS, JavaScript) and goes into these in greater detail than Digital Multimedia. It also covers server-side scripting in some depth.

Cascading Style Sheets

W3C’s overview of CSS, includes pointers to the standards, of which CSS 2.1 is currently the most relevant, although some parts of CSS 3 should become available in time.
HTML 4.01 Specification

The XHTML 1.0 spec relies on HTML 4.01 for the meanings of XHTML elements and attributes, so in effect this is part of the XHTML specification – the most interesting part, in fact.
IANA: MIME Media Types

The official list of Internet Media Types (though IANA still seem to prefer to call them MIME types).
Uniform Resource Identifiers (URI): Generic Syntax

The online (plain text file) version of IETF RFC 2396 from 1998: the formal definition of URIs, which includes URLs as a subset.
XHTML 1.0: The Extensible HyperText Markup Language (Second Edition)

This document is the official definition of XHTML, but all it really says is that XHTML is the same as HTML 4, except for some small changes needed to make it XML. You need to know about these, but if you want to know what all the elements and attributes are, it’s the HTML 4.0 specification that you need.
