/**
|
|
* Manages a frontend inline CSS or JavaScript resource.
|
|
*
|
|
* If possible, the resource will be served as a static file for better performance. It can be
|
|
* tied to a specific post or it can be 'global'. The resource can be output, static or inline,
|
|
* to one of four locations on the page:
|
|
*
|
|
* * `head-early`: right AFTER theme styles have been enqueued
|
|
* * `head` : right BEFORE the theme and wp's inline custom css
|
|
* * `head-late` : right AFTER the theme and wp's inline custom css
|
|
* * `footer` : in the footer
|
|
*
|
|
* The first time the class is instantiated, a static callback method will be registered for each
|
|
* output location. Inside each callback, we'll iterate over any/all instances that are assigned
|
|
* to the current output location and perform the following steps:
|
|
*
|
|
* 1. If a static file exists for the resource, go to the next step. Otherwise, try to create
|
|
* a static file for the resource if it has `data`. If it doesn't have `data`, assign it to
|
|
* the next output location and then move on to the next resource (continue).
|
|
* 2. If a static file exists for the resource, enqueue it (via WP or manually) and then move on
|
|
* to the next resource (continue). If no static file exists, go to the next step.
|
|
* 3. Output the resource inline.
