Add The Code Below To The Bottom Of Functions.php File or Custom Function Plugin

*IMPORTANT – If you have Debug set to TRUE in WP-Config, the “jquery code” will throw a php error.  I’ll try to get a fix, but this code is really popular.

(may be added to Socrates Toolkit Shortly)

//Remove Query Strings from Static Sources

function soc_remove_qstrings_css_js( $src ) {
	if ( strpos( $src, 'ver=' ) ) {
		$src = remove_query_arg( 'ver', $src );
	}
	return $src;
}

add_filter( 'style_loader_src', 'soc_remove_qstrings_css_js', 9999 );
add_filter( 'script_loader_src', 'soc_remove_qstrings_css_js', 9999 );

// Replace Jquery - Will Break Masonry Template
function soc_remove_jquery() {
	if (!is_admin()) {
		wp_deregister_script('jquery');
		wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js', false, '1.8.3');
		wp_enqueue_script('jquery');
	}
}
add_action('init', 'soc_remove_jquery');

Video Placeholder Trick

If you don’t want a video to load upon page load, use this code to make it load upon click.

Just take a screenshot of your video, upload it and replace the sample video poster link with the image path.  Then replace the source src with your MP4 link.

<div align="center">
<video poster="https://socratestheme.com/videoimage.png" preload="none" controls="controls" width="100%" height="auto">
<source src="https://socratestheme.com/video.mp4" type="video/mp4" preload="none" />
</video></div>
