CssInliner::removeImportantAnnotationFromNodeInlineStyle │ private │ WC 1.0

Removes the "!important" annotations out of the inline style declarations, eventually by rearranging declarations. Rearranging needed when !important shorthand properties are followed by some of their not !important expanded-version properties. For example "font: 12px serif !important; font-size: 13px;" must be reordered to "font-size: 13px; font: 12px serif;" in order to remain correct.

Method of the class: CssInliner{}

No Hooks.

Returns

null. Nothing (null).

Usage

// private - for code of main (parent) class only
$result = $this->removeImportantAnnotationFromNodeInlineStyle( $node ): void;
$node(DOMElement) (required)
