Elementor is a great plugin I was searching for a long time. There is no other flexible page builder like Elementor at the moment. To make full width page you may customize and use Blankslate Theme. I recommend Blankslate theme because it has very minimum css and other settings and this will help fast loading of website. Please go through this detailed tutorial on how to make Elementor Full Width Page Template https://www.youtube.com/watch?v=DvcAIrDIz1s&t=274s Also watch https://www.youtube.com/watch?v=aQY0lb2l0Bs&t=16s to learn how to make full width background slider with elementor. Thanks
