A favicon (favorite icon) is a small image that serves as branding for your website to help visitors easily identify your page, especially when multiple tabs are open. A favicon increases brand awareness and improves user experience.
If you have long pages requiring a lot of scrolling, then you can enable a Back to top button for your Zest theme.
This allows you to ease your customers' shopping experience in one click by adding a floating back to top button that allows them to navigate back to the top of the page easily.
Steps:
In the theme editor (Customize), click Theme settings.
