NOTE In 0.3.0, all filters have changed (changed dash to underscrore): css_flags_countries, css_flags_regions, css_flags_exclude and css_flags_cachetime.

Usage

The total CSS file size is 4 MB, and you don't want to send all that data back to the users, so you must use one of the following filters in your plugin or theme.

css_flags_countries: Load flags for one or more countries

add_filter('css_flags_countries', function() {
	return array('no'); // Array with ISO_3166-1_alpha-2 country codes: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements
});

css_flags_regions: Load the flags for one or more regions. You can choose between europe, oceania, africa, asia, northamerica, southamerica and middleeast.

add_filter('css_flags_regions', function() {
	return array('europe'); //europe, oceania, africa, asia, northamerica, southamerica, middleeast
});

css_flags_exclude: Exclude some countries from the list. This filter must be used in combination with the css_flags_countries or css_flags_regions filters

add_filter('css_flags_exclude', function() {
	return array('eu');
});

css_flags_cachetime: Change the cache time, default it's 7200 (60x60x2 = 2 hours)

add_filter('css_flags_cachetime', function() {
	return 172800; // 2 days
});

If you must (but you shouldn't), you can load all the CSS flags using the following:

add_filter('css_flags_countries', function() {
	return array('all'); // load all country flags (don't it's 4MB)
});

Example 1

Using this filter in your (child) theme functions.php

add_action( 'init', function() {
	add_filter('css_flags_countries', function() {
		return array('no');
	});
});

CSS Flags will add the following CSS (note the .css-flag prefix):

/* CSS generated in 0.002 seconds. */
.css-flag.no {
	background-image: url('data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZpZXdCb3g9IjAgMCAxMTAwIDgwMCI+DQo8cGF0aCBmaWxsPSIjZWYyYjJkIiBkPSJtMCwwaDExMDB2ODAwaC0xMTAweiIvPg0KPGcgZmlsbD0iI2ZmZiI+DQo8cGF0aCBkPSJtMzAwLDBoMjAwdjgwMGgtMjAweiIvPg0KPHBhdGggZD0ibTAsMzAwaDExMDB2MjAwaC0xMTAweiIvPg0KPC9nPg0KPGcgZmlsbD0iIzAwMjg2OCI+DQo8cGF0aCBkPSJtMzUwLDBoMTAwdjgwMGgtMTAweiIvPg0KPHBhdGggZD0ibTAsMzUwaDExMDB2MTAwaC0xMTAweiIvPg0KPC9nPg0KPC9zdmc+DQo=');
	height: 100%;
	width: 137.5%;
	background-size: 100% 100%;
}
.css-flag.no-landscape {
	height: 100%;
	width: 137.5%;
}
.css-flag.no-portrait {
	height: 72.727272727273%;
	width: 100%;
}

I bet you can CSS and HTML better than me, but you could display the flag using this in your (child) theme:

<style type="text/css">
	.box {
		width: 32%;
		/*float: left;*/
	}
	.flagbox {
		width: 120px;
		height: 120px;
		display: inline-block;
		vertical-align: middle;
	}
	.flag {
	    margin: auto;
		display: inline-block;
		vertical-align: middle;

		border: 1px solid #e5e5e5;
		box-shadow: inset 0px 0px 0px 2px #fff;

	}
</style>

<div class="box">
	<div class="flagbox"><span class="flag no no-portrait"></span></div>
</div>

Example 2

Load the CSS Flags for the five Nordic countries and their autonomous regions: Norway (no), Sweden (se), Denmark (dk), Findland (fi), Iceland (is), the Faroe Islands (fo), Greenland (gl) and Aaland (ax)

add_action( 'init', function() {
	add_filter('css_flags_countries', function() {
		return array('no','se','dk','fi','is', 'fo', 'gl','ax'); // ISO_3166-1_alpha-2 codes: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements
	});
});

Only load the Scandinavian flags ('no','se','dk') by removing flags from the loaded list

add_action( 'init', function() {
	add_filter('css_flags_exclude', function() {
		return array('fi','is', 'fo', 'gl','ax'); // ISO_3166-1_alpha-2 codes: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements
	});
});
