Widget Template HTML Filter

The siteorigin_widgets_template_html_{$id_base} filter changes the HTML that a widget's template outputs, where {$id_base} is the widget's base ID. Use it for small changes to the HTML. For larger changes, change the widget's template file with the Template File Filter.

/**
 * @param string $template_html The template HTML.
 * @param array $instance The widget instance.
 * @param SiteOrigin_Widget $widget The widget object.
