CssInliner::normalizeStyleAttributesOfAllNodes │ private │ WC 1.0

Parses the document and normalizes all existing CSS attributes. This changes 'DISPLAY: none' to 'display: none'. We wouldn't have to do this if DOMXPath supported XPath 2.0. Also stores a reference of nodes with existing inline styles so we don't overwrite them.

Method of the class: CssInliner{}

No Hooks.

Returns

null. Nothing (null).

Usage

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