The header options in the customizer menu has options for the sticky header and sticky header color. For more header settings, please use the Ariyah Options Panel instead.
Sticky Header
The stick header option lets you keep the header area on top while you scroll down on the page. This ensures that navigation is always visible and accessible.
Sticky Header Background
Option to change the color and transparency of the sticky header when scrolling. This is particularly helpful when the header is transparent.
