Subscription Administrators and Editors can create a banner that appears at the top or bottom of the page on both classic and modern pages.
Go into the help editor window by clicking the green Add Help Item button.
In the Viewer / Media Type drop down, select Banner.
Select the banner icon from the Icon drop down.
Give it a title, then click into the Banner Content field to start adding your content.
You can change the background color of the banner and the text color under Banner Settings.
You can position the banner at the top of the screen or the bottom with the Position drop down.
You can also configure if the banner will appear in the help panel.
The banner can also be configured to auto show on load, which will automatically display the banner when a user visits the page. Note: Once a user clicks the "x" to close out the banner, the banner will no longer autoload.
