Custom CSS not being applied: How to target tags inside the dropdown menu search

I hope you are well today and thank you for your question.

Your custom CSS code is wrong and needs to be redeveloped.

Also, to make the required changes you have to develop more custom CSS code and add it in the Custom CSS option of Ivory Search plugin settings on the path Admin Area -> Ivory Search -> Settings -> Settings

If you are not a developer, you can consider hiring a developer to develop it. You can hire a developer from any freelance site or WordPress agency.

You can also consider hiring me to develop it for you using the form https://ivorysearch.com/custom-work/
