WP_HOME and WP_SITEURL

// If we're behind a proxy server and using HTTPS, we need to alert WordPress of that fact
// see also http://codex.wordpress.org/Administration_Over_SSL#Using_a_Reverse_Proxy
if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https') {
	$_SERVER['HTTPS'] = 'on';
}
// (we include this by default because reverse proxying is extremely common in container environments)

if ($configExtra = getenv_docker('WORDPRESS_CONFIG_EXTRA', '')) {
	eval($configExtra);

Misc

In the customize editor, it’s possible to add CSS like:

.smaller50 {
	max-width: 50%;
}


.smaller25 {
	max-width: 25%;
}

They can then be applied in the additional settings of a block, but they must be tailored for the tag (not every css works with every tag…).

Add an internal link
