CSS spec­i­fi­ca­tions

This page contains descriptions of all specifications that the the CSS WG is working on. See the “current work” page for a compact view and how to give feedback.

Media Queries

Description
Media Queries is an enhancement of the @media rules of CSS and the “media” attribute in HTML. It adds parameters such as size of display, color depth and aspect ratio. This is because within a class of media (such as TV sets) there can still be important variations. It is related to the work on CC/PP, but is a much more light-weight and limited solution.

Selectors

Description
Selectors describes the element selectors in CSS3. Selectors are used to select elements in an HTML or XML document, in order to attach (style) properties to them. It includes the selectors of CSS1 and CSS2 and extends them with new proposals, that allow, for example, elements to be selected based on whether they are the immediate sibling of another element, or whether they are the only child element of their kind.

CSS 2.1

Description
CSS Level 2 Revision 1 corrects errors in the 1998 Recommendation of CSS level 2 and adds a select few highly requested features originally planned for CSS3, which have already been widely implemented. But most of all CSS 2.1 represents a “snapshot” of CSS usage: it consists of all CSS features that are implemented interoperably for HTML and XML at the date of publication of the Recommendation.

Description
Many primarily visual devices are in fact capable of making sound as well, sometimes even of very high quality. In CSS3 those multimedia capabilities will be available to designers. The audio module contains properties for attaching background sounds to elements and sound effects to state transitions, such as link activation or "hovering" over an element. Expected possibilities include overlaying multiple sounds, positioning a sound left or right in stereo space and playing a sound in a loop.

CSS Basic Box Model

Description
The Box Model describes the layout of block-level content in normal flow. When documents are laid out on visual media (e.g. screen or paper), CSS represents the elements of the document as rectangular boxes that are laid out one after the other or nested inside each other in an ordering that is called a flow. The flow can be horizontal (typical for most languages) or vertical (often used for Japanese & Chinese).

Description
Cascading and Inheritance describes how values are assigned to properties. CSS allows several style sheets to influence the rendering of a document, and the process of combining these style sheets is called "cascading". If no value can be found through cascading, a value can be inherited from the parent element or the property's initial value is used.

CSS Object Model

Description
The DOM specifies the functions that are found in several programming libraries (and browsers) to manipulate HTML, XML & CSS documents. Programmers can call them from their programs rather than write their own. Some of those functions deal with adding & deleting rules and changing properties in CSS style sheets. These APIs form the CSS Object Model or CSS-OM. They are useful for stand-alone programs as well as for scripts and applets. DOM level 2 contains two chapters on the CSS-OM (CSS Object Model) and the CSS WG will develop a level 3 CSS-OM.

CSS Positioning

Description
Positioning defines “absolute,” “fixed” and “relative” postioning. These are ways to take an element out of the normal flow of elements (as specified by the box model) and put it somewhere else: either relative to the root or some other element's box (absolute), relative to the viewport (fixed), or simply slightly offset from where it would normally be (relative).

CSS Presentation Levels

Description
Presentation Levels introduces a way to step forward and backward through multiple renderings of the same document, which is especially useful for slide show presentations (highlight list items one at a time) and outline views (show more or less detail). The model is that each element has a presentation level and three styles (three states): one for when the browser is at a lower presentation level, one for an exact match and one when the browser's presentation level is above that of the element. The browser must offer the user an easy way to increase and decrease the browser's level.

CSS Reader Media Type

Description
This module was dropped in March 2008. The keyword 'reader' is a media type for use in Media Queries (similar to 'screen', 'print', 'projection', etc.). Devices that might choose to apply rules inside '@media reader' are devices like screen readers, that display a page on screen and speak it at the same time, or display the page and simultaneously render it on a dynamic braille device. The properties that apply to this media type are therefore the combination of the properties for screen, speech and braille.

Grid Layout

Description
Grid Layout allows to set up a flexible design grid for an element so that the descendants of the element can be positioned relative to that grid and thereby be aligned to each other in two dimensions. Areas of the grid can be assigned names both for ease of use and to create a level of indirection that facilitates reordering of elements. Like the other grid/template modules, this module builds on frame-based layout ideas that started in 1996 and produced, among other things absolute positioning in CSS level 2. The Grid Layout module thus has a large overlap with Multi-column Layout, Template Layout, Flexible Box Layout, Grid Positioning, and Regions, but doesn't replace them. It is expected, however, that the six modules can eventually be condensed to just three: Multi-column, Flexible Box, and a third one for grids/templates/regions.

Regions

Description
Regions allow a box to look other than rectangular. It defines two complementary methods: several boxes can form a chain where each is filled with the text that overflows from the previous one; and a box can define a shape inside its rectangle that constrains all text to the inside of the shape. It is expected that these features will eventually be moved into one of the grid/template modules, possibly the Grid Layout module, to reduce the number of separate specifications.

CSS Speech

Description
Speech contains properties to specify how a document is rendered by a speech synthesizer: volume, voice, speed, pitch, cues, pauses, etc. There was already an ACSS (Aural CSS) module in CSS2, but it was never correctly implemented and it was not compatible with the Speech Synthesis Markup Language (SSML), W3C's language for controling speech synthesizers. The ACSS module of CSS2 has therefore been split in two parts: speech (for actual speech, compatible with SSML) and audio (for sound effects on other devices). The speech properties in CSS3 will be similar to those in CSS2, but have different values. (The old properties can still be used with the deprecated 'aural' media type, but the new ones should be used inside the new 'speech' medium, as well as in style sheets for 'all' media.)

CSS style Attribute Syntax

Description
The syntax of CSS rules in HTML's “style” attribute is strictly speaking not part of CSS3, but is mentioned here, because it is produced by the CSS working group. It was made necessary, because XHTML 1.0, in contrast to HTML 4.0, doesn't define the syntax of CSS rules in its style attribute. However, the specification is valid for all similar attributes (e.g., those in SVG), not just for HTML.

CSS Text

Description
Text contains the text-related properties of CSS2 (underlining, justification, text wrapping, etc.) plus several new properties, many for dealing with text in different languages and scripts (line breaking, kashida, hyphenation, etc.). It includes (and replaces) the proposal in the International layout draft. Also see the Line module for things like vertical alignment within a line, line height calculation and styles for first-line/first-letter. The Text module reached CR status in 2003, but very little was implemented. Some common typography required too many properties, while many combinations of values were not useful. The rewrite started in 2004 and should result in the same functionality, but with fewer properties and better defaults. The Text module has been split into three parts: Text, Writing Modes, and Line Grid.

It also describes the order of letters inside the line (bi-directionality) and the rotation that may occur for certain letters inside vertical text.

CSS Flexible Box Layout

Description
The Flexible Box Layout Module defines the 'box' and 'inline-box' keywords for the 'display' property, which cause an element to be displayed as either a column or a row of child elements. Additional properties determine the order of the child boxes (left to right, bottom to top, etc.) and how space is distributed over the children and the spaces between them. The module is primarily intended for forcing rows of controls in a GUI to equal height or width.

CSS Transitions Module

Description
The Transitions Module defines a property to animate the transitions between pseudo-classes (e.g., when an element enters or leaves the ':hover' state). During a given delay, certain property values gradually change from the old value to the new, rather than instantaneously, as in level 2.

CSS Animations Module

Description
The Animations Module specifies which properties change their values during an animation, what values they take successively, and during how much time. It does not define what causes a particular animation to start, only what happens during one. (Compare this to the Transitions module, which also animates properties, but between state changes, i.e., pseudo-classes.)

SVG

Some properties are specifically for styling SVG (or similar graphics languages) and are defined in the SVG spec, rather than in a CSS module. They can be used together with other properties in a style sheet, but usually don't apply to the same elements. They specify things such as the color of strokes and fills, and the shape of the ends of strokes.
