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.
