Welcome to the DevGuru Cascading Style Sheets Quick Reference guide.
This is a useful 108 page reference source that defines and explains all of the various style sheet properties,
and displays sample code.
Cascading Style Sheets (CSS) is a declarative language that is used to enhance the HTML language.
The World Wide Web Consortium (W3C) has published a set of standards referred to as the
"Cascading Style Sheets, Level 1" standards.
This Quick Reference documents these standards and their degree of implementation in the latest
versions of Netscape Navigator and Microsoft Internet Explorer.
No proprietary style properties are documented.
The concept of CSS is that you can declare a style property inside the
<HEAD> ... </HEAD> portion of an HTML file
and associate that property with an HTML tag or some specified keyword.
For example, a font color can be associated with the P in <P>.
Wherever that <P> tag appears in the
<BODY> ... </BODY> portion of the HTML code,
the font color style property is applied.
The effects of declaring several style properties can cascade together into creating the final
appearance of the page.
Used properly, CSS can allow you to create an entire Web site with a consistent appearance
in design.
Prior to the acceptance of the W3C Cascading Style Sheet Level 1 standard,
developers discovered the hard way that browsers supported Cascading Style Sheets in a rather inconsistent manner.
Fortunately, if an older (pre W3C standard) version of a browser does not recognize CSS code,
it usually ignores.
Style sheets have now become part of mainstream Web programming.
Internet Explorer Versions 4.0 and later, and Netscape Navigator Versions 4.0 and later
are fairly compatable with most of the W3C standards.
The key word is most.
Neither Internet Explorer nor Netscape recognize all of the W3C standard.
And to further complicate matters, some companies have created and implemented their own
proprietary style properties.
So, certain browser compatibility problems still remain.
The Guru has tested all of the W3C Cascading Style Sheet Level 1 standards.
By clicking on the
link that is found with each style property, you can see a list of which HTML tags
actually worked for the Guru for that particular property.
A whole suite of proposed new style properties and values looms on the horizon.
So, the future of Cascading Style Sheets promises to be very exciting.
