Repeating Grid Lines

While using the grid-template-columns property, if you do not want to specify the size of each column repeatedly, there is the repeat property that you can use to specify the size of several columns at one go.

grid-template-columns : repeat(8,4fr);

This above property will make 8 columns each column taking the space represented by the given fraction.
