The Editor provides the abbility to use rulers. The ruler is a single line making it easy to set a proper module position on a lesson page.

A very helpful feature is the possibility of snapping the module to the ruler. For example: In order to set a 50px left position for all modules, turn on the snapping mode, set the vertical ruler position to 50px, drag the relevant modules and they will be easily snapped to the ruler.

Note: To change the ruler position, simply double-click on it, enter the required value and select OK.
