Hello,

You can edit header from the customizer, going to Dashboard > Appearance > Customize > Header.

Hello,

To have all provided customizer settings, the Kirki plugin is recommended. You can install and active the plugin manually from Dashboard > Plugins > Kirki or simply click on the Get Started with Bosa to install and active all the recommended plugins automatically including kirki.
