First of all, i love the product in general. I have added a lot of CSS myself, such as the styling for the categories of a blog post. I run into a problem and I cannot solve it myself. I have edited the categories as text to look like buttons, but I can’t hide the comma in between the categories.
Regretfully there is no option to remove it at the moment. It would require custom development. I would suggest you contact a developer who can assist you with your concern. Please note that we don’t provide custom development support. It is out of the support scope.

Please note that the code provided in the above thread serves as a guide only and is to help you in getting started so implementing it and maintaining the code will be out of our support scope and for further maintenance for new possible versions of the theme that may cause the customization to break, you will need to hire a developer.
