"grid-template-column allows you you to set up how the grid is constructed. You can do it in percentages, pixels, or fr which stands for fractions. With with two 1fr we made it so each piece will take 50% of the space minus the gutters which it will calculate for you. If we did 1fr 2fr 1fr the first column would take 25%, the second 50%, the third 25%. The math works like flex-grow."

The word 'with' is repeated twice.
