For all of our notices we use a background image, usually 940px wide. When there's a sidebar, this gets truncated to 720px by the notice container. However, with the new responsive design, the notice container will continue to shrink (then briefly enlarge again when the sidebar disappears then shrink again) when making the browser smaller. As there's no easy way (that I know of?) to have a notice background image change when the notice panel shrinks, it'd make sense for us that the notices disappear completely when below a certain resolution. Is that possible? What would be even better would be the possibility to create "mobile notices" that ONLY show when the resolution is below a certain size. That way we'd have our normal notices above a certain resolution then make these disappear and then how their mobile counterpart (probably without images) when below that resolution.
