Remove CSS in code

Hi lesurfeur

Try it with the use_default_gallery_style filter hook in your theme’s functions.php file. This will remove the styles from all the WordPress galleries, and the post thumbnail galleries displayed by this plugin.

add_filter( 'use_default_gallery_style', '__return_false' );

Try it with this in your theme’s functions.php if you want to remove the styles from this plugin’s galleries only:

// filter run before styles are printed for a related posts gallery
add_filter( 'related_posts_by_taxonomy_gallery', 'related_gallery_return_false' );

function related_gallery_return_false( $args ) {

	// don't print styles for related posts by taxonomy gallery
	add_filter( 'use_default_gallery_style', '__return_false' );

	// reset gallery style for other galleries
	add_filter( 'gallery_style', 'related_gallery_reset_filter' );

	return $args;
}

function related_gallery_reset_filter( $style ) {

	// use default styles for galleries
	add_filter( 'use_default_gallery_style', '__return_true' );

	return $style;
}

btw:
consider creating a child theme instead of editing your theme directly – if you upgrade the theme all your modifications will be lost. Or create a plugin with the code above.
