Hi, thanks. I found a solutin here:
https://www.ads-software.com/support/topic/video-settings-twenty-seventeen-theme/
After creating child them it’s enough to add this code lines to style.css file
/* Make sure play/pause button can be clicked on smaller screens */
.wp-custom-header-video-button {
z-index: 10;
}
and this code to file functions.php:
/*
* Change the minimum screen size to use the video header
*/
function twentyseventeenchild_video_size( $settings ) {
$settings[‘minWidth’] = 100;
$settings[‘minHeight’] = 100;
return $settings;
}
add_filter( ‘header_video_settings’, ‘twentyseventeenchild_video_size’ );
it works!
