Elementor templates are pre-designed, customizable page layouts that users can import into their WordPress websites to quickly create visually appealing and functional pages. They are essentially building blocks that help users design their website without starting from scratch, offering a range of options from individual sections to complete page layouts. Elementor Template Kits, specifically, are collections of templates designed for specific website types or niches, like a real estate website or a portfolio. 

Templates are a helpful tool that can help you save time when creating or editing documents. Instead of designing pages, sections, containers etc. from scratch, you can use templates to implement your designs quickly and ensure a consistent look and feel across your site.

In Elementor, templates also refer to the standard parts (e.g. header, footer) of your website.
