I am working with Magento ver. 220.127.116.11.
There is a pre-existing CSS that we cannot see or edit. This is problematic because it changes the custom CSS that I want to implement for a certain page. We have the pre-existing code, but it is very messy and I would rather start from scratch and use my CSS in the CMS editor page.
Is there a way to remove, edit, improve or disable the pre-existing code for CMS pages?
