Different Versions Of Css
CSS or Cascading Style Sheets had been known as one of the most popular and widely used style sheet language in the market today
. Part of the reason why, according to many
Web design Philippines experts, is because of its simplicity yet powerful styling language.
Because of its success as a style sheet language, CSS had continuously evolved to accommodate the kinds of modern practices that different
web developer Philippines has come.
Different Versions of CSS
CSS has various levels and profiles. Each level of CSS builds upon the last, typically adding new features and typically denoted as CSS 1, CSS 2, and CSS 3. Profiles are typically a subset of one or more levels of CSS built for a particular device or user interface. Currently there are profiles for mobile devices, printers, and television sets. Profiles should not be confused with media types, which were added in CSS 2.
Capabilities of the First CSS
The first CSS was published in December of 1996, and was subsequently standardized by the W3C. Among its features are basic CSS capabilities such as font properties such as typeface and emphasis, color of text, backgrounds, and other elements, text attributes such as spacing between words, letters, and lines of text, alignment of text, images, tables and other elements, margin, border, padding, and positioning for most elements, as well as unique identification and generic classification of groups of attributes.
However, W3C had now removed its standardization of CSS 1. This is to make way of a new CSS standard that is still commonly used today, which is CSS 2.
CSS 2
CSS level 2 specification was developed by the W3C and published as a Recommendation in May 1998. A superset of CSS 1, CSS 2 includes a number of new capabilities like absolute, relative, and fixed positioning of elements and z-index, the concept of media types, support for aural style sheets and bidirectional text, and new font properties such as shadows. The W3C no longer maintains the CSS 2 recommendation.
Dawn of a New Styling Language
Instead of defining all features in a single, large specification like CSS 2, CSS 3 is divided into several separate documents called "modules". Due to the modularization, different modules have different stability and are in different status.
As of March 2011, there are over 40 CSS modules published from the CSS Working Group. On 7 June 2011, the CSS 3 Color Module was published as a W3C Recommendation.
