History Like HTML, CSS is standardized by the W3 consortium. CSS is an open, independent and freely usable standard. As with HTML, a working group exists for CSS who concerns itself with development of the standard. This is being done in accordance with W3C rules.
CSS comes in different versions. CSS level 1 was released in 1996, and republished with corections in 1999. CSS level 2 appeared in 1998 and built on CSS level 1. CSS level 2 adds support for different output media. CSS 3 is currently in development and will be split up in modules.
Tutorial As with most products, HTML coding evolves
and improves into new versions. The "normal" or regular HTML coding that people are used to is version 3.2. The current version available to use is version 4. Version 4 is mainly suited to work in a browser that is version 4 or above.
CSS or Cascading Style Sheets are command tags used to format web page text, objects, and layout. As HTML4 was introduced, CSS became an important part of it.HTML4 and CSS have the same browser problems as the previous version. Compatibility. Different browsers will understand only certain tags. What works in one, may not work at all in another. If two browsers do understand the same tag, they may or may not produce different results.
CSS Cascading Style Sheets (CSS) is a good way to specify the styles of fonts and other page elements on your sites. It makes it easier for you to update styles too, because when done right, you only need to make a single change to update the styles on multiple pages and elements.
Another bonus is that your visitor's browser needs to load less data per page, helping you reduce your data transfer usage while serving the same information. That means you'll be able to accommodate more site visitors without having to spend more on data transfer. Your pages will also load faster.
is CSS In our CSS tutorial you will learn how to use CSS to control the style and layout of multiple Web pages all at once.
CSS stands for Cascading Style Sheets . Styles define how to display HTML elements.

Cascading Style Sheets
Style sheets for the Web have been proposed and developed for several years, but only recently have gained wide notice. The reason is that style sheets are useless unless browsers support them, and no widely used browser did until Microsoft began offering partial support for Cascading Style Sheets (CSS) in version 3.0 of the Internet Explorer. Support for style sheets is provided in IE 3.0 and higher, and in Netscape 4.0 and higher.This section provides an overview of CSS, including the advantages of using style sheets, their limitations, and a guide to using them.
Web Developer's Virtual Library Style Sheets allow you to control the rendering -e.g. fonts, colors, leading, margins, typefaces, and other aspects of style-of a Web document without compromising its structure. Cascading Style Sheets (CSS) are a simple style sheet mechanism that allows authors and readers to attach style to Web pages. It uses common desktop publishing terminology which should make it easy for professional as well as untrained designers to make use of its features. Visual design issues, such as page layout, can thus be addressed separately from the Web page logical structure.
Tutorial House of Style The House of Style has several cascading style sheets tutorials, with explanations, excercises and worked examples to get you up and running with style sheets as quickly as possible.While more a reference than a tutorial, our Complete CSS Guide covers all of the CSS2 specification, including an extensive explanation of how style sheets work in the
introduction. The Guide is available online here at the House of Style for free. As well, we have a version of the Guide, incorporating all the browser support information for the various selectors and properties, and including a special extra section on "Real World CSS".
All right, cascading style sheets are a new way of formatting your page layout, text, fonts, images, and almost anything you put on the page. As you saw above, they allow you to postition things on your page down to the exact pixel. Also, if a style is declared in the head section of a page, a change to the style changes the style on the entire page. We'll get to the details in later tutorials, but here is the general idea:
Let's say you created a style for a heading tag, <H3>. In your style, you set the color of your H3 tags to red.
Sizzling HTML, Style Sheets
Adding cascading style sheets (CSS) to web pages is a relatively simple process, although the topic as a whole is fairly sizeable. Technically speaking, style sheets are not part of HTML but act as an extension to it. Consequently there is a whole new syntax to learn, as well as the HTML used to implement style sheets. In addition to this, browsers have only recently started supporting style sheets and there are differences in the extent and manner of implementation.First of all we will look at how to use style sheets in your web pages, followed by a detailed review of the presentation and formatting options available, and finally we will cover the differences between the browsers and some further tricks to bear in mind.
Positioning The answer is a bunch of CSS properties collectively called CSS positioning. CSS positioning can be used to do a lot of cool things. Most "Dynamic HTML" techniques use and manipulate CSS positioning properties to achieve flashy effects. Some uses of positioning properties can even be used to replace despised HTML frames, but for this tutorial we'll concentrate on their use for layout.
In this tutorial, we'll take a look at the theory behind CSS-based page layout, and explain how to do things according to the specification. In the next tutorial, we'll put this theory to the test and see how you can work around the numerous bugs in most modern browsers in order to achieve the effects you desire.
Positioning Part II CSS positioning a feature of CSS2 that is implemented better than many others in Internet Explorer and Navigator. This isn't very high praise for either browser, however, as it's not implemented very well at all. None the less, it can be made to do what you want it to do. In the following pages, we'll examine a technique that will create multi-column layouts for Web pages that works with all current CSS-supporting browsers.
When this tutorial was first written, Internet Explorer 5.5 had not yet been released, and the technique described was slightly different.
Tutorial Style sheets provide a means for authors to specify how they wish documents written in a markup language such as XML or HTML to be formatted. For example, an author might wish to specify that a document should be green on pink - this could be done using CSS, an established standard for styling documents.
HTML isn't designed for styling documents - when you write an HTML document, you are specifying only the content that the element contains. Given the piece of HTML: <H1>A heading</H1>, you have specified nothing about the way the element should be rendered, only that the element is a level 1 heading.
Tutorial To use CSS for layout effectively, it helps to know how it's used to position page content. This article gives an overview of the methods and rules that govern visual rendering in the CSS2 specification. It also points out some things to watch out for.Although the specification applies to any device for displaying web pages, this article focuses on how it works in browsers. Many details are left out for the sake of simplicity. For a definitive reference, see the standards publication.
Stylesheets Tutorial Cascading stylesheets are a new-ish technology that promises to make the Web a better place by allowing you to control layout like never before, to make smaller, faster pages, and to easily maintain many pages at once.
Steve Mulder, author of "Web Designer's Guide to Stylesheets," created this five-day stylesheets tutorial which - modesty aside - kicks butt.
Your journey begins with a quick trip through the basics of cascading stylesheets - everything you have to know to get started quickly.
Tricking Browsers and Hiding Styles
Although some feel the browser wars are behind us, their sad legacy persists. Every time an author has to code a workaround to make Navigator 4.x happy, every time a Web page comes up differently in different browsers, an echo of the wars lives on. Fortunately, there are ways to take advantage of these same browser flaws to make our lives a little easier. It might not seem like much, but we need to take our victories where we can.
Hiding Style Sheets from old browsers
In these web design articles I?ve mentioned CSS from time to time and devoted a couple of articles specifically to the topic
- a basic introduction to CSS and a look at using CSS to describe the layout of web pages. I have tried to emphasise the importance of separating structure and presentation of a web page; in the first of those articles I noted that ideally CSS should be used to describe every aspect of a page?s appearance.
There are two enormous problems with this: the first is that only version 4 and higher browsers support CSS; the second is that CSS support is variable and idiosyncratic even in those browser versions which support it. Netscape 4.x browsers are particularly problematic.
Structure and Rules There are some cases where the inner selector does not inherit the surrounding selector's values, but these should stand out logically. For example, the margin-top property is not inherited; intuitively, a paragraph would not have the same top margin as the document body.Pseudo-classes and pseudo-elements are special "classes" and "elements" that are automatically recognized by CSS-supporting browsers. Pseudo-classes distinguish among different element types (e.g., visited links and active links represent two types of anchors). Pseudo-elements refer to sub-parts of elements, such as the first letter of a paragraph.
For Beginners CSS stands for Cascading Style Sheets. This is a simple styling language which allows attaching style to HTML elements. Every element type as well as every occurance of a specific element within that type can be declared an unique style, e.g. margins, positioning, color or size. So you might consider these style sheets as templates, very similar to templates in desktop publishing
applications. There are many ways to link style sheets to HTML, each carrying its own advantages and disadvantages. New HTML elements and attributes have been introduced to allow easy incorporation of style sheets into HTML documents.
Dave Raggett's Introduction to CSS This is a short guide to styling your Web pages. It will show you how to use W3C's Cascading Style Sheets language (CSS) as well as alternatives using HTML itself. The route will steer you clear of most of the problems caused by differences between different brands and versions of browsers.
For style sheets to work, it is important that your markup be free of errors. A convenient way to automatically fix markup errors is to use the HTML Tidy utility. This also tidies the markup making it easier to read and easier to edit. I recommend you regularly run Tidy over any markup you are editing. Tidy is very effective at cleaning up markup created by authoring tools with sloppy habits.
or CSS Tutorial 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.Using CSS, you can define colours, backgrounds, borders, margins, alignment, fonts, sizes and loads of other things for almost any part of your web pages.
Our focus is Cascading Style Sheets (CSS), and we have tried to compile a useful source of information, examples and links to other external resources.
CSS is a flexible, cross-platform, standards-based language used to suggest stylistic or presentational features applied throughout entire websites. In their most elegant forms, CSS are specified in a separate file and called from within the HTML header area when documents loads into the CSS-enabled browser. Users can always turn off the author's styles and apply their own or mix their important styles with the authors. This points to the "cascading" aspect of CSS.
Quick Tutorial A style sheet is made up of style rules that tell a browser how to present a document. There are various ways of linking these style rules to your HTML documents, but the simplest method for starting out is to use HTML's STYLE element. This element is placed in the document HEAD, and it contains the style rules for the page.
That while the STYLE element is a good method of experimenting with style sheets, it has disadvantages that should be considered before one uses this method in practice. The advantages and disadvantages of the various methods are discussed in the section on linking style sheets to HTML.
Each rule is made up of a selector--usually an HTML element such as BODY, P, or EM--and the style to be applied to the selector.
Hypergurl CSS Introduction and Tutorial
Cascading stylesheets allow you to control the layout of your page to look almost exactly as wanted. To make pages smaller in size and to easily maintain many pages at once.
Your content is viewable and understandable to almost all browsers as those that recognize cascading stylesheets use it.Separate form and structure. Maintain or update many pages at once. Have your site browser friendly and apply fancy effects to your pages, such as having two visited link colors, overlapping text or control text sizes.With the use of Cascading stylesheets your HTML remains clean and simple and the CSS code controls appearances.
There aren't many web developers who have not at least tried using Cascading Style Sheets (CSS) to define typography and simple page attributes such as background and text color. These days more and more developers are pushing CSS even further, eschewing tables and embracing CSS as a web page layout tool. In this article I'll explain why CSS is in many ways preferable to using tables for layout, and then I'll show you some CSS layout techniques using a complete re-coding of the Apple Internet Developer home page as an example.
