Add Template area

Custom Microthemer option. Enter the name of a grid-area, then use the grid control canvas to define its size and position. Microthemer will then generate valid grid-template-areas ASCII art for you.

The grid-template-areas property is most useful when writing CSS grid code by hand - to visually see the structure of the grid. But Microthemer's grid control serves that function, so most users will not need to set grid-template-areas.
