If your site is live to the public and you would like to make design/functional changes to the store without having your customers see the process (or possibly have your changes interfere with their shopping experience), you can use the Store Status function to prevent access to the store temporarily.
By closing the store, you can create an 'under construction' page that the public will see when they go to your domain.
Furthermore, you can limit access to the store so only you and your staff can see the site during the design and functionality edits.
To close the store:
Go to Settings > Design > Store Status.
Check the Store Closed radio button.
Create the message you would like your customers to see in the WYSIWYG editor.
Click Save at the top right to close the store.
As an alternative to closing the entire store, you can also select to only close the checkout portions of your site by selecting the "Checkout Closed" radio button. This will still allow your customers to browse your products and site in general but will place your Store Closed Message if the customer tries to proceed to checkout.
Additional Information:
