Animate a custom banner
A call-to-action banner is a great way to indicate an announcement at the top of your site and encourage your site visitors to do something. You can place banners anywhere and style them however you like, but this lesson walks through the structure and animation of a typical alert banner in Webflow (as inspired by Apple.com) — one that slides out from under the navbar on page load. We’ll also show you how to animate the banner so it changes color after the slide animation.

Animate a custom banner in Webflow shows you how to build and animate a notification or promotional banner element on your site. Banners are commonly used for announcements, alerts, or promotional messages, and adding a smooth entrance animation makes them feel more polished and intentional.
The typical approach is to create the banner element — usually a fixed or sticky bar at the top or bottom of the page — and then use Webflow's Interactions panel to set up a page load trigger. The animation might slide the banner in from off-screen, fade it in, or drop it down from the top.
You can also animate the banner out when a user dismisses it, using a click trigger on a close button that plays a reverse animation and then hides the element.
This kind of interaction is a good example of how Webflow's visual interaction builder handles common UI patterns without requiring custom JavaScript for the animation itself.
