If you are just about ready to go live and want to start the process of either connecting your domain or migrating a blog but don't want your full site accessible just yet you can create a landing page that visitors will see while you finalize your design.
1. The first thing your will want to do is to create a new Page. To do so, click on the "Site" tab on the top-left, you will see, on the left, a list of Pages within your site.
You can click "+" icon to and create a new page.
If you double-click the Page, you will be able to change its name.
2. To set up a simple landing page I am going to add a background image to both the mobile and desktop designs
3. You can add text or other elements to design the landing page to let your visitors know that your new site is launching very soon. Then under the Canvas tab, set the Canvas Type to "Window Height" on both mobile and desktop views to allow the canvas to fill the dimensions on any given page.
4. Finally, select the 3 dot's next to the page name and choose "Set as Homepage".
As an additional feature, you can create a simple contact form to capture clients while the rest of your site is being built. To learn how to create a contact form you can check out this article: Contact Form
