A very useful function is Grid which gives the possibility of aligning the size and position of different modules on a given page. To enable the Grid feature in the editor, simply go to Presentation > Preferences, check the "Use grid" box and define the grid size in pixels. You may also enable this option in the main panel of the editor under menu. The Grid option may be enabled/disabled and it does not influence the modules’ current position. The grid’s density is changeable and the modules' size and position are being aligned to the grid’s node. The minimum value of Grid is 2px.
