This is an example of a landing page with a full-width, no sidebar layout. When you are creating a page, you can select the full-width template option. It is built-in just for you! You can set this just as a regular page or set it to be your home in Settings > Reading. I have a tutorial in my theme documentation showing you how to set this up and also how to add a slider to your landing page. The options are endless!
