For card sizes other than A5, edit the size value in @page, and the height and width properties of body.
Add contents to each face. The simplest approach is to add an image called front.png of the same dimensions as the card.
Generate a PDF from the HTML + CSS. If using Prince, it's as simple as prince index.html card.pdf.
Take the PDF to a printer, and ask them to print as many copies as you need.

To change all classes for an element:

document.getElementById("MyElement").className = "MyClass";

document.getElementById("MyElement").className += " MyClass";

First, Lets find out what version of PHP we're running (To find out if it's the default version).

To do that, Within the terminal, Fire this command:

which php

	# Don't show errors which contain full path diclosure (FPD)
	# Use that line only if PHP is installed as a module and not per CGI
	# try using a php.ini in that case.
	# Change mod_php5.c to mod_php7.c if you are running PHP7
	<IfModule mod_php5.c>
	php_flag display_errors Off
	</IfModule>

	# Don't list directories
	<IfModule mod_autoindex.c>

	//* Add walker class that displays menu item descriptions
	class Menu_With_Description extends Walker_Nav_Menu {
	function start_el(&$output, $item, $depth, $args) {
	global $wp_query;
	$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';

	$class_names = $value = '';

	$classes = empty( $item->classes ) ? array() : (array) $item->classes;
