I’ve created a function to add a class to the body, however if should only apply to a single page ID. This normally wouldn’t be a problem, but it is breaking the layout for other pages. Filter Function add_filter(‘body_class’,’add_blog_to_body_class’); function add_blog_to_body_class($classes) { $classes[] = ‘blog’; return $classes; } My Condition (that isn’t working) function add_blog_to_body_class($classes) … Read more
