Building a Custom Button Block

We will create a block that adds a button with our theme's styling.

Using a PHP class for block registration

Since we will be defining multiple blocks for our theme, instead of registering them one by one, we can create a PHP class to reduce code duplication. This will also help avoid naming conflicts with other functions and variables of WordPress or any third party plugins.

In functions.php, create a class called ExcellenceBlock. The class will have a __construct function which includes the action and filter hooks.
