W3C CSS Validation Service; a free service that checks Cascading Style Sheets (CSS) in (X)HTML documents or standalone for conformance to W3C recommendations. Note: If you want to validate your CSS style sheet embedded in an (X)HTML document, you should first check that the (X)HTML you use is valid.

Tutorials, books, mailing lists for users, etc. can be found on the learning CSS page. For background information on style sheets, see the Web style sheets page. Discussions about CSS are carried out on the (archived)

Currently Internet Explorer does not support CSS based gradients. This tool is updated whenever implementation methods are changed. This generator uses the latest implementation of Mozilla gradients
found here. The CSS3 Gradient Generator was created as showcase of the power of CSS based gradients as well as a tool for developers and designers to generate a gradient in CSS. CSS gradients generate an image result, meaning the result of a CSS gradient can be used anywhere an image can be used, be it a background-image, mask, border, or list item bullet.

2010-05-28T01:17:00-08:00 - This example shows how to use CSS3's transform and transition properties to scale and enlarge an image when the mouse rolls over it, in an animated fashion.
2010-03-17T06:34:00-08:00 - With the advent of CSS3's comes support for linear gradients, which offer a fast and lightweight way of adding gradients to your page. It can be used in conjunction with a gradient image to get the best of both worlds.
2010-01-01T23:04:00-08:00 - Among CSS3's handy new features is the border-radius property, which offers a clean and easy way of adding rounded corners to elements on the page. The rounded corner look can be applied to any or all four corners of an element, and even works with elements with a background image.
2009-11-12T10:16:00-08:00 - This versatile CSS image enlarger lets you display image thumbnails that resize to their original dimensions when the mouse rolls over them. Only one image is needed in each case.
2009-08-19T05:18:00-08:00 - CSS3 supports a new "box-shadow" property that makes it very easy to add shadows to elements on your page, such as images, DIVs and SPANs. Lets see how to take advantage of it!
2009-07-06T02:43:00-08:00 - This menu turns a nested UL list into a horizontal drop line tabs menu. The top level tabs have rounded corners thanks to the use of two transparent background images
2009-06-13T18:54:00-08:00 - This menu turns a nested UL list into a horizontal drop line menu, with each sub menu appearing as a single row of links beneath its parent menu. To polish it up, the menu uses a touch of jQuery magic to apply a nice slide down effect to each sub menu as it is revealed.
2009-04-07T00:38:00-08:00 - This corporate blue themed menu uses the sliding door technique to create 2 states. While it works perfectly fine against a white background, for black background pages, the tabs reveal a thick white outline around its edges.
2009-03-20T20:57:00-08:00 - This is a simple yet professional looking multi level side menu. Markup wise it's just a regular nested UL list, turned into a drop down menu using a very small JavaScript code.
2009-01-08T08:20:00-08:00 - This horizontal CSS menu goes with a minimalist approach, by applying just a thick border underneath each link to give it style. It supports easy centering (or right aligning) on the page, just by changing the text-align property in the CSS. No images are used, just good old code.
CSS tutorial - Introduction. .CSS is a formatting language, used to provide more customised web pages and make it easier to make multiple pages use the same style. The acronym stands for Cascading Style Sheets. All current browsers can handle CSS, and it is the best Web page formatting language produced to date. Some very popular browsers do not handle it as well as they should (see the section on browser problems) but largely support is good and developers are tending to use it much more often.

Maxdesign Discusses float, lists, selectors and other CSS issues
css-discuss is primarily intended to be a place for authors to discuss real-world uses of CSS. This doesn't preclude discussions of theory, or nifty cutting-edge tricks that show off the power of CSS, or even talking about (X)HTML, DOM, and so forth. However, it's greatly appreciated if such discussions have some practical payoff, even if it's just teaching other list members a little bit more about how CSS works. While we don't forbid discussions of the future direction of CSS, the World Wide Web Consortium runs a listserv explicitly for that purpose called www-style. It's probably a better place for those kinds of discussions.

W3 Style Sheets Style sheets represent a major breakthrough for Web page designers, expanding their ability to improve the appearance of their pages. In the scientific environments in which the Web was conceived, people are more concerned with the content of their documents than the presentation. As people from wider walks of life discovered the Web, the limitations of HTML became a source of continuing frustration and authors were forced to sidestep HTML's stylistic limitations. While the intentions have been good -- to improve the presentation of Web pages -- the techniques for doing so have had unfortunate side effects. These techniques work for some of the people, some of the time, but not for all of the people, all of the time The syntax of style data depends on the style sheet language.

XSLT, (Extensible Stylesheet
Language Transformations), which is a language
for transforming XML
documents into other XML documents. XSLT is designed for use as part of XSL, (Extensible
Stylesheet Language),
which is a stylesheet language for XML. In addition to XSLT, XSL includes an XML
vocabulary for specifying formatting. XSL specifies the styling of an XML
document by using XSLT to describe how the document is transformed into another
XML document that uses the formatting vocabulary. XSLT is also designed to be
used independently of XSL. However, XSLT is not intended as a completely
general-purpose XML transformation language. Rather it is designed primarily for
the kinds of transformations that are needed when XSLT is used as part of XSL.

script against the Document Object Model (DOM) in web browsers. The idea is that everything starts with the element(s) in question, selected through id
or CSS selectors, and then perform various methods on it, such as adding or removing classes, events etc.
Document Object Model (DOM) is a platform and language-independent standard object model for representing HTML or XML and related formats.
