.navbar { display: none; }

Adding Custom CSS

Please add your custom CSS code into the next field from WordPress customizer: 

WordPress Admin > Appearance > Customize > Additional CSS

By using this method you can be sure to not lose any custom code on theme update. Alternatively, you can use a dedicated plugin for this job. For instance: Simple Custom CSS and JS.

Note:

Our theme supports a child theme and we have an empty child theme included in the full theme package ( see Premium Design Assets > cloudios-child.zip  ). Child themes are better for complex customizations or when you need to change PHP code as well.
