Sticky Header

Navigate to Appearance > Customize > Header > Sticky Header to set your header and or top bar to ‘stick’ at the top of the window. With this setting turned OFF, the header of your site (Logo, navigation menu, social) will scroll under and disappear as your visitors scroll down the pages of your site. With it turned ON, the header will always be visible at the top of the browser window and the content will scroll under it.
