This CSS Reference shows the basic syntax of a CSS rule; lists all standard CSS properties, pseudo-classes and pseudo-elements, @-rules, units, and selectors, all together in alphabetical order, as well as just the selectors by type; and allows you to quickly access detailed information for each of them. It not only lists the CSS 1 and CSS 2.1 properties, but also is a CSS3 reference that links to any CSS3 property and concept standardized, or already stabilized. Also included is a brief DOM-CSS / CSSOM reference.
In CSS, a replaced element is an element whose representation is outside the scope of CSS. These are a type of external object whose representation is independent of the CSS. Typical replaced elements are <img>, <object>, <video> or form elements like <textarea> and <input>. Some elements, like <audio> or <canvas> are replaced elements only in specific cases. Objects inserted using the CSS content properties are anonymous replaced elements.
Added in HTML5, the HTML <canvas> element can be used to draw graphics via scripting in JavaScript. For example, it can be used to draw graphs, make photo compositions, create animations, or even do real-time video processing or rendering.
The CanvasCaptureMediaStream.requestFrame() method forces a frame to be captured and sent to the stream. This allows to capture partially rendered frames.
The CSS Object Model is a set of APIs allowing to manipulate CSS from JavaScript. It is the pendant of DOM and HTML APIs, but for CSS. It allows to read and modify CSS style dynamically.
