Is there a way for a plugin to add an attribute to the tag of a theme?

You can probably use the language_attributes filter (from the language_attributes() function) to add it. It should receive an output like lang=”en” and you can add to it before printing to the <html> tag: add_filter( ‘language_attributes’, function( $attr ) { return “{$attr} manifest=\”manifest.appcache\””; } ); or without a anonymous function add_filter( ‘language_attributes’, ‘wpse140730_add_manifest_to_language_attributes’ ); function wpse140730_add_manifest_to_language_attributes($output) … Read more
