The Material Design Lite (MDL) grid is a component for laying out content for varying screen sizes. The MDL grid is defined and enclosed by a container/div element. A grid has 12 columns in the desktop size screen, 8 in the tablet size screen, and 4 in the phone size screen, where each size has predefined margins and gutters. Cells are laid out in sequential manner in a row, in the order they are defined, with following exceptions:

  • If a grid cell is not fit for the row in one of the screen sizes, it flows into the following line.

  • If a grid cell has a specified column size equal to or larger than the number of columns for the screen size, it takes up the entire row.

MDL provides various CSS classes to apply various predefined visual and behavioral enhancements to the grid. The following table lists down the available classes and their effects.
