My current challenge involves modifying the background color of a specific custom HTML WordPress block. However, when I make changes to one block, it affects the background color of all other custom HTML blocks on different pages.
Here is the CSS code I am using:
#main.site-main.post-single.order-first{ background-color: #212529; }
I was anticipating that only the background color of the custom HTML block on this page would be altered, but to my surprise, the change also applied to a different page with its own custom HTML block.
