Applying what you have learned so far
As an exercise, consider this section of the https://rwd.education website:
Figure 5.12: Can you use your grid knowledge to lay out this section?
If you look in the Start folder for this chapter's code, you will see that, currently, those sections are just one under the other. Try to amend the code for that section with Grid. Perhaps think about how you could easily have it showing one or two of those sections when screen space is limited, and the layout that is shown in the preceding screenshot when space allows.
There's already a working draft for CSS Grid Layout Module Level 2. The principle benefit it brings with it is the ability to have subgrids: grids within grids that can inherit the track sizing of their parents. You can read the current specification here: https://www.w3.org/TR/css-grid-2/.
Let's move on to some even more advanced Grid techniques now.
