Vaadin is a web application framework for Rich Internet Applications (RIA).
Vaadin enables easy development and maintenance of fast and
secure rich web
applications with a stunning look and feel and a wide browser support.
It features a server-side architecture with the majority of the logic
running
on the server. Ajax technology is used at the browser-side to ensure a
rich
and interactive user experience.

*
* CSS 2.1 has the following selector types (where "SN" is
* shorthand for "the selected node"):
*
*
* - Universal (i.e. "*"): Affected by the removal of SN from the document.
* - Type (i.e. "div"): Affected by the removal of SN from the document.
* - Descendant (i.e. "div span"): Affected by changes to SN or to any of its ancestors.
* - Child (i.e. "div > span"): Affected by changes to SN or to its parent.
* - Adjacent Sibling (i.e. "table + p"): Affected by changes to SN or its previous sibling.
* - Attribute (i.e. "div.up, div[class~=up]"): Affected by changes to an attribute of SN.
* - ID (i.e. "#header): Affected by changes to the id attribute of SN.
* - Pseudo-Elements and Pseudo-Classes (i.e. "p:first-child"): Affected by changes to parent.
*
*
* Together, these rules dictate that the smart (but still lazy) way of removing elements from the computed style
* cache is as follows -- whenever a node changes in any way, the cache needs to be cleared of styles for nodes
* which:
*
*
* - are actually the same node as the node that changed
* - are siblings of the node that changed
* - are descendants of the node that changed
*
*
* Additionally, whenever a style node or a link node with rel=stylesheet is added or
* removed, all elements should be removed from the computed style cache.
