Granim.js vs. Multiple.js vs. Ping-API vs. Synfig Studio Comparison Chart

An experiment in sharing background across multiple elements using CSS. If you want to accomplish a "background sharing across multiple elements" effect in HTML/CSS without any coordinates processing by JavaScript, Multiple.js is the answer. Note that icons and text at lighter layers have gradient-color from darker layers, creating the illusion of an underlying violet layer. In addition to that, layers pass the background image (girl) with equal transparency so that layers can not be superimposed on each other. All these things can be implemented in CSS. Add a gap between elements to make sure that the background remains in the same position. Toggle background image/gradient to get idea how it looks. Miss random layers to make sure that elements are independent. Expands background to viewport's size and displays in every element appropriate chunk, exactly what is needed! Background can be successfully expanded to full viewport size.
