Hi honeyrandhawa. The mobile view sidebar configurations are in responsive.css. You could copy that file to a child theme and make your adjustments there. If you do copy it to a child theme you’d also need to copy function alx_styles to your child theme functions.php file:
function alx_styles() {
wp_enqueue_style( 'style', get_stylesheet_uri() );
if ( ot_get_option('responsive') != 'off' ) { wp_enqueue_style( 'responsive', get_template_directory_uri().'/responsive.css' ); }
if ( ot_get_option('custom') == 'on' ) { wp_enqueue_style( 'custom', get_template_directory_uri().'/custom.css' ); }
wp_enqueue_style( 'font-awesome', get_template_directory_uri().'/fonts/font-awesome.min.css' );
}
Then change the line that loads the responsive.css file from “get_template_directory_uri()” to “get_stylesheet_directory_uri()” so it loads the file from your child theme.
