Announcement banner
An announcement banner spans the width of your storefront and is displayed on every page. Use announcements to promote important messages.
Announcement banners are great for informing customers of things such as changed store hours, flash sales, new locations, or highlighting a holiday bundle. This banner can include an image, plain text, and can link to a destination. If a customer dismisses the announcement banner, the banner doesn't reappear for the rest of the session.
note
You can have one active announcement banner on your storefront.
