Now, related to that here I will explain how to modify the appearance of cookies bar by using the css code.

Making modifications to notifications or cookie notifications in blogger with the aim of making them look cooler and easier to see by visitors is a good thing.

To enhance the appearance of these cookies bar you can make modifications using the css code, for more details, please follow the steps below.
