Thank you for making this plugin available. I have slightly changed the CSS to give a flatter appearance. I would like to go one step further and have the banner push the page content down (when used in the top position) so that it appears above all current content until closed or timeout. I have seen it done elsewhere for cookie consent banners but haven't been able to find a way to make yours do the same. What code should I modify and in what way to make this happen?
