Hi there!

All changes such as change background, change font, or add new elements, etc you can do by yourself editing css and html at your own risk.

We don't provide any services, paid or unpaid, for editing themes for individual users.

However, we provided an intelligible instruction on how to use developer tools to help you make changes to the style.css file here:
