我正在尝试从Wordpress主题上的滑块中删除视差效果，但没有太多运气，有人可以建议我需要对以下代码进行更改以删除视差吗？谢谢你的帮助！
add_shortcode( 'full_screen_slider', 'bravo_full_screen_slider' );
function bravo_full_screen_slider( $atts, $content ){
extract(shortcode_atts(array(
'slider_categories'=>'',
'padding_top'=>'160',
'padding_bottom'=>'160',
),$atts));
$output= "";
if(empty($slider_categories))
$tax_query = '';
else
$tax_query = array( array('taxonomy' => 'slider_categories', 'field' => 'slug', 'terms' => explode(',', $slider_categories), 'operator' => 'IN') );
$args = array(
'post_type'=>'slider',
'tax_query' => $tax_query,
'posts_per_page' => -1
);

if (has_post_thumbnail(get_the_ID()) ) {
$attachment_id = get_post_thumbnail_id(get_the_ID());
$attachment_info=wp_get_attachment_image_src( $attachment_id,'full');
