// CREATE VIEW RATIO OBJECT
var $viewRatio = viewRatio({
    maxWidth: 1920, // STOP ZOOMING IF WIDTH IS BIGGER THAN 1920px
    minWidth: 480,  // STOP ZOOMING IF WIDTH IS SMALLER THAN 480px
    width: 1920,    // ZOOM WILL BE BASED ON THIS WIDTH
    zoomRatio: 0.5, // ZOOM WILL BE 0.5 SLOWER

$viewRatio.scale();

// FIRE SCALE EVENT ON WINDOW RESIZE

First of all making something like this was hard due to cross browser support and it still has some problems so its in development stage for now .

• Edge & IE shows scrollbars on both sides
• Using fixed position in scaled element causes element to be not fixed. ( See Issue )
