It is possible to snap a module to the grid while dragging or resizing it. While dragging the module, each of its edges is snapped to grid.
There are two important rules to follow when resizing the module and using the snap function::
1. All edges of the module must overlap the grid lines, which means the module's position must cover the grid.
2. The module's dimensions must be the multiplicity of the grid size, including padding or the module's borders.
The snapping function is also available for Rulers – both when rulers are and aren't visible.
