I wanted to figure out the fastest way to load non-critical CSS so that the impact on initial page drawing is minimal.

TL;DR: Here's the solution I ended up with: https://github.com/filamentgroup/loadCSS/

For async JavaScript file requests, we have the async attribute to make this easy, but CSS file requests have no similar standard mechanism (at least, none that will still apply the CSS after loading - here are some async CSS loading conditions that do apply when CSS is inapplicable to media: https://gist.github.com/igrigorik/2935269#file-notes-md ).

Seems there are a couple ways to load and apply a CSS file in a non-blocking manner:

	*/

	<?php
	class Webdev {
	function runAsFunction($name,$params = []){
	global $modx;
	if($s = $modx->getObject('modSnippet', [
	'name' => $name,
	])){
	$s->loadScript();
	$f = $s->getScriptName();
	// $params = array('foo' => $foo);

	A few blocks of .htaccess code to help improve your websites performance and/or functionality. I would recommend reading about each section and applying if required instead of applying everything.

	The more code in your .htaccess the more your server needs to process BEFORE the HTML starts being served.
