The billboard is characterized by its position below the horizontal navigation bar. The large dimensions give the advertiser plenty of space for design and information. The best way to get into the user’s field of vision. Through a “Mouse Over” effect, the billboard expands into the content of the advertising medium and thus offers the possibility to address the user through additional effects or information. With “Mouse Out”, the advertising medium closes automatically.
