Hello,
Thank You so much for your Patience!
If you are using a Car Demo, they run on the native style.css and css/js Files and can be found in the Package/HTML Folder with the names: demo-car.html Template.
These are the following Folders/Files you will need for the Niche Templates:
css/ Folder
images/ Folder (However, you can delete the Images inside this Folder according to your Preference, but don’t delete the images/icons/ Folder)
include/ Folder (However, you can delete the rs-plugin/ Folder)
js/ Folder
demos/car/ Folder
style.css File
You can simply delete the other files depending on what you want to use. Additionally, simply rename the demo-car.html File to index.html File so that this file is viewed as your Default Homepage.
Hope this Helps!
