WooContentProcessor::prepare_css │ public │ WC 10.8.0

Filter CSS for the email. The CSS from the email editor was already inlined. The method hooks to woocommerce_email_styles and removes CSS rules that we don't want to apply to the email.

Typography properties (font-size, font-weight, line-height, letter-spacing) are stripped because the email editor theme controls all typography via theme.json. Leaving these in the WooCommerce CSS would override the editor's heading sizes and weights.

Method of the class: WooContentProcessor{}

No Hooks.

Returns

String.

Usage

$WooContentProcessor = new WooContentProcessor();
$WooContentProcessor->prepare_css( $css ): string;

$css(string) (required)

CSS.
