To make this component work you must follow these steps:
Add a Page trigger and select Page load
Select the Loader 1 [Hide] animation inside When page finishes loading
Position loader1_component inside page-wrapper

Note:
Sometimes there may be a bug where the website briefly flashes before the loader is displayed. To avoid this add the following custom code in your Site settings > Custom Code > Head code
