How to change my navbar colour from white to others?

I've tried to change it but still remain same.

I can't upload my image to show an example.

You will need to overwrite the css by copying the nav bar class into your own css file

I would also click into settings option in top tool bar and change the theme to the basic bootstrap version which is themeless as this will also help me as I was once in the same place you are now

Take a look at this tutorial and you will see how do add custom classes to your own style sheet

Thanks again Chris

Chris, I've made it when I'm change to new version BS3 to BS4. My Navbar change colour from colourless to purple

Excellent ? good work Amie
