Fix with the extension "FixedObject" A Desired WYSIWYG Web Builder object at a given position (relative to the browser window) on your side. This object is, and that's the exciting, when scrolling in the browser window will always be at your specified location. Thus, for e.g. funny advertising graphics or messages placed in one of the four corners of the browser window. Enter an object (other than extensions), but also a complete level with multiple objects, simply on the current object ID and then it will be fixed according to your settings in the desired location in the browser window (see examples on the left / top and right / bottom).
