HTML slide page-transition animation system. Implements multiple slide-switching effects (slide-left, slide-right, slide-up, slide-down, zoom, flip, fade, blur, elastic-scale) for single-page HTML presentations, while coordinating per-element entrance animations so that the slide transition and element animations play simultaneously — never sequentially — eliminating the double-animation problem. Use for: HTML PPT/Slides authoring, single-page presentation animation systems, smooth slide transitions that do not break element entrance animations. Keywords: slides switch transition animation ppt stagger entrance overlap.
