Interface CssStyleSheet

All Superinterfaces:

StyleSheet

public interface CssStyleSheet
extends StyleSheet

An object implementing the CSSStyleSheet interface represents a single CSS style sheet.

A CSS style sheet consists of CSS rules, each of which can be manipulated through an object that corresponds to that rule and that implements the CSSStyleRule interface, which in turn implements CSSRule. The CSSStyleSheet itself lets you examine and modify its corresponding style sheet, including its list of rules.

In practice, every CSSStyleSheet also implements the more generic StyleSheet interface. A list of CSSStyleSheet-implementing objects corresponding to the style sheets for a given document can be reached by the document.styleSheets property, if the document is styled by an external CSS style sheet or an inline style element.

getOwnerRule

CssRule getOwnerRule()

If this style sheet comes from an @import rule, the ownerRule attribute will contain the CSSImportRule. In that case, the ownerNode attribute in the StyleSheet interface will be null. If the style sheet comes from an element or a processing instruction, the ownerRule attribute will be null and the ownerNode attribute will contain the Node.

Returns:

If this style sheet is imported into the document using an @import rule, the ownerRule property will return that CSSImportRule, otherwise it returns null

deleteRule

void deleteRule(int index)

Used to delete a rule from the style sheet.

               int index)

Used to insert a new rule into the style sheet. The new rule now becomes part of the cascade.

rule - The parsable text representing the rule. For rule sets this contains both the selector and the style declaration. For at-rules, this specifies both the at-identifier and the rule content.

index - The index within the style sheet's rule list of the rule before which to insert the specified rule. If the specified index is equal to the length of the style sheet's rule collection, the rule will be added to the end of the style sheet.
