Not so long ago, font tags (which are evil) provided a web designer’s only means of formatting an HTML document’s text for presentation within web browsers such as Microsoft Internet Explorer™, Opera™ or Mozilla Firefox. The trouble with font tags was that they were not only notoriously unreliable for presenting any given piece of information in the way initially intended by its author; they also bloated file sizes to almost insupportable proportions. In fact, even the text size setting of a browser could make a page’s content overlap or

An old saying goes: “There are two types of people: those who divide people into two types and those who don’t.” I am definitely in the former group. For example, I might say there are two types of people: those who read Web pages and those who create them. Of course, some of us do both, but the vast majority of the Web-using public doesn’t know or care about the messy underpinnings of HTML, Web servers, browser compatibility issues, and all the rest. They care about just one thing: the information on the page. If a page loads too slowly, if the

In a sense, nobody is in charge of the web. The web is an open standard, with no restrictions on who can post content, or what that content should be about. The web belongs to everybody, and so it belongs to nobody. The openness and decentralization of the web is one of its greatest strengths. But it wouldn't work at all without some sort of standard way of encoding the information. That's where the World Wide Web consortium (W3C) comes in. The W3C is an international, vendor-neutral group that determines the protocols and standards for the web. They

Simply put, Cascading Style Sheets (CSS) is a way to separate a document's structure from its presentation. The benefits of this can be quite profound: CSS allows a much richer document appearance than HTML; CSS saves time—you can create or change the appearance of an entire document in just one place; and its compact file size makes web pages load quickly. Eric Meyer, a past member of the CSS&FP Working Group and an internationally known expert on HTML and CSS, tackles the subject with passion and delivers a comprehensive and thorough update to

CSS is the abbreviation for Cascading Style Sheet. A style sheet simply holds a collection of rules that we define to enable us to manipulate our web pages. CSS can be applied to our pages in many ways, however the most powerful way to employ CSS rules is from an external cascading style sheet. When used in this manner the full power of CSS can be brought to control the design and appearance of our work from a single controlling location, which makes it easy to update our site on a global basis. It would be foolish, impracticable and probably

Excerpted from "Status of this Document" and "Introduction" sections: "Comments during the SMIL review period suggested that the relationship between SMIL and CSS should be more clearly explained. This note provides a detailed explanation of the relationship between SMIL layout and CSS. It updates a Note from June 15. Most changes are editorial. A section on mapping z-index values from SMIL basic layout to CSS has been added." "SMIL basic layout has a few multimedia-related options that the initially text-based CSS does not cover yet. These will be

After first announcing that there will be a new version of Internet Explorer, Microsoft went mysteriously quiet. After digesting the announcement, what everyone wanted to know was - what’s going to be in it? We already had a release date of sorts (a beta release in the summer). But no feature list. The ensuing silence masked an internal confusion. Subsequent announcements on the IEBlog were bland at best. Another empty post regarding IE and Standards was met with dismay by the web development community. Today it began to emerge, what developers

Since the idea of CSS2.2 was raised, there’s been some discussion as to what it should encompass, who should be responsible for the spec, and what it should be called; here’s what I think: First, it doesn’t matter what it’s called. Whether it’s referred to as CSS2.2, CSS2.1+, CSS3 Interim, or whatever, makes no difference. It doesn’t need to have a name at all; the important thing is that we have it. Second, it doesn’t need to be an official recommendation from the W3C; in fact, it may be easier if it’s not. The optimal solution

I recently posted a preview of the CSS3 colour module on my own blog, but avoided using any actual examples. This was because of the things that have been implemented, the true power isn’t really seen using a simple example. With opacity and the HSLA/RGBA colour models, any elements that have been coloured just look like they fade to a lighter tint if there is only a white background behind it. Support for SVG colour keywords has also existed for a long time, just without being accepted by the validator. To show the true flexibility of CSS3 colour,

Cascading Style Sheets Level 3 is known as CSS3 for short. Cascading Style Sheets level 3 is the most recent approach of CSS which has a modularized approach which helps to differentiate the connections between the different parts of the specification and also helps in attaining a systematic approach with more flexibility. The popularity of Cascading Style Sheets Level 3 is because of its modularized capability which gives greater flexibility. That is in other words the Cascading Style Sheets Level 3 has the capability of building of specific tests

Imagine this: overnight, the W3C makes CSS3 a standard, and the browsers end their differences (IE included) and support everything in CSS3. How will this affect you? What magical things that CSS3 offers will bring your webpages to life? For instance, CSS3 gives us cross–browser opacity, standardized Image Replacement (via display: icon), and automatic box and text shadows, not to mention being able to control the resizing of a window through CSS. And there’s a lot more where that came from. But then you wake up and realize that complete

Abstract CSS (Cascading Style Sheets) is a language for describing the rendering of HTML and XML documents on screen, on paper, in speech, etc. To color elements in a document, it uses color related properties and respective values. This specification describes the properties and values that are proposed for CSS level 3. It includes and extends them from properties and values of CSS level 2. Status of This Document This specification is one of the "modules" for the upcoming CSS level 3 (CSS3) specification. It not only describes the color related

Abstract Presentation levels are integer values attached to elements in a document. Elements that are below, at, or above a certain threshold can be styled differently. This feature has two compelling use cases. First, slide presentations with transition effects can be described. For example, list items can be progressively revealed by sliding in from the side. Second, outline views of documents, where only the headings to a certain level are visible, can be generated. Status of This Document This section describes the status of this document at

Abstract "Ruby" are short runs of text alongside the base text, typically used in East Asian documents to indicate pronunciation or to provide a short annotation. This document proposes a set of CSS properties associated with the 'Ruby' elements. They can be used in combination with the Ruby elements of HTML [RUBY]. Status of This Document This specification is one of the "modules" for the upcoming CSS level 3 (CSS3) specification. It has been developed by the CSS Working Group which is part of the Style activity (see summary). It contains

I’ve written a number of posts about CSS3 on my personal blog, so when I was asked to write on CSS3.info I jumped at the chance. To get the quick disclaimer out of the way, my day job is working for Opera Software as their Chief Web Opener. Any thoughts are my own, and any use of CSS3 properties doesn’t imply that they will or will not be supported by Opera in an upcoming release, unless otherwise explicitly stated. With that out of the way, I was discussing the difference between opacity and RGBA in the office, and thought that it would be
