Add Page Slug to Body Class in WordPress
One of my favorite feature when it comes to theme development in WordPress is the concept of body class. For a deliberate design, you not necessarily need to use these classes but it can be useful in a lot of cases.
One of the scenario if you want to target a specific page. The need for page targeting in CSS can happen in a lot of situation and it is better to create a slug based class than using the default ID based.
By default, you only get post-id-* classes and you can’t identify the page correctly; this is where the body_class filter come in picture.
You can create any conditional check if needed. If you want to know more about the body_class filter please visit the official documentation!
