<?php
add_action( 'tgmsp_before_slider_output', 'tgm_custom_slider_theme' );
function tgm_custom_slider_of_madness( $id ) {
// If not the proper slider ID, do nothing. Change to match your slider ID.
if ( '324' !== $id ) return;
// Dequeue the default styles.
wp_dequeue_style( 'soliloquy-style' );
// You can enqueue any stylesheet you would like here for the slider. For best results, target the slider uniquely via IDs.
