+/**
+ * Override Elementor CSS order
+ * Normally, the Sage CSS is the last to load but we need Elementor's post specific CSS
+ * to load after the theme so it can override things like the padding. Elementor's default
+ * frontend CSS contains 10px padding on all populated elements, which messes with our
+ * designs so we override this in our theme. However, to override it, we are forced to use a
+ * CSS selector with high specificity in our theme's CSS:
+ * .elementor-column-gap-default > .elementor-row > .elementor-column > .elementor-element-populated
+ * When Elementor generates its post-xx.css files for custom styling set on a page, the specificity
+ * of this CSS rule is the same as ours so it can never override ours unless it is the last stylesheet
+ * to load. The desired loading order is:
+ * 1) Elementor Global / Frontend CSS
+ * 2) Sage Main CSS (Theme CSS)
+ * 3) Elementor post specific CSS (post-xx.css)
+ *
+ * Elementor has a hook when registering CSS files - https://code.elementor.com/hooks/elementor-css-file-name-enqueue/
+ * However, I couldn't get this to work properly with add_action and we need to use the post ID (get_the_ID()), which
+ * doesn't always seem to be available. I need to figure out where this hook should be added so that it is ready...
+ *
+ * For now, the solution is quite low-level and we inject a dependency of our theme's 'sage/main.css' CSS file into
+ * Elementor's post specific CSS file just before the stylesheets are printed. By having our theme as a dependency,
+ * Elementor's post-xx.css file is forced to load after the theme's CSS...
+ *
+ * TODO: revisit this and see if there's a better solution. See issue here: https://github.com/elementor/elementor/issues/7658
