// KISS: expandCollapse()
//
// Simple function to show or hide an element (elementname given by function
// arguments). Uses CSS to hide/display elements, the start element should
// be hidden on first load (display: none). Checks, whether an element is being
// displayed and switches it to display: none and vice versa.
