In order to learn how Grid works Rachel Andrew has put together lots of small examples, and publishing them as a resource for anyone else interested in this emerging specification. Grid gives us some new terminology along with additional CSS Properties and values. The Grid Layout spec is broken into smaller chunks, rather than large examples that show lots of different aspects of the specification at once.
All examples include a screenshot (taken in Chrome), code sample and link to the worked example. You will need a supporting browser to view these examples. Current supporting browsers and how to enable support in those browsers can be found on the Igalia site.Grid by Example
