Summary

This chapter served to show us what it takes to implement features on CSS Grid and what it takes to create polyfills for CSS on our own. We’ve talked about the need, or lack thereof, for polyfills and how they can cause more harm than help to us.

We can create CSS polyfills quickly with PostCSS and Browserify. Still, often we shouldn’t, as the specifications of the polyfilled features are often either not complete or browser vendors are about to deliver an implementation themselves.

In the next chapter, we’ll look at some popular CSS frameworks. We’ll inspect their grid implementations and see how they might use CSS Grid if they’re using it at all. Looking at CSS Grid in the wild helps us understand how some of the foremost CSS experts understand CSS Grid.
