Static block is the piece of codes written in HTML that is used for various purposes like banner of advertising, promoting, social media link, blog etc. You can display this block through out the site in a particular section of the site suppose between header and body.
Here I am guiding you to add a static block in your Magento CMS page. Magento provides 3 handles partcularly to edit the CMS pages.
a) Home page handle b) 404 page handle c) CMS page handle
For a static block to be shown on home page we will use home page handle block. For other pages we will use CMS page handle.
Suppose you want to display a static block in all CMS pages of your store. Then follow the steps given as below.

You have set up your static block and now you can call it to any CMS page by calling the identifier.
