Html_Processing_Helper::remove_wrapper_handled_classes │ public static │ WC 1.0

Remove from an element the class names whose styles the renderer applies to the wrapping table cell.

Background and border classes are resolved by the CSS inliner wherever they appear. The wrapping cell keeps the block's original class list and receives the same styles inline, so leaving these classes on the inner element paints them a second time. For an opaque color that is invisible, but a translucent palette color composites over itself and renders as a visibly darker band inside the cell's padding.

Method of the class: Html_Processing_Helper{}

No Hooks.

Returns

null. Nothing (null).

Usage

$result = Html_Processing_Helper::remove_wrapper_handled_classes( $html ): void;

$html(WP_HTML_Tag_Processor) (required)

Tag processor positioned on the element to clean.
