If you dont like or need the standard event banner in the WordPress EventManager you can easily hide it with a short CSS code. For this you need to log in to your wordpress account and then go to the frontend of your site. Here you need to click at the “Customizer” in the top menu. If you want to go there from the backend, you will have to click the “Design” point in the left menu and click “Customizer”.
Now another menu will open on the left side of your website. There you should find a point like “custom CSS” at the very bottom of the menu. Here you should add the following code that will hide the event banner on desktop and mobile view.
That´s it. You can change the code if you only want to hide it on mobile or desktop.
