Welcome to part-3 of the series. We will start where we had left and will first add a layout.css inside the components folder. This will contain our global styles.
Rest of the chapter is exclusive content and will be in my upcoming book Gatsby Cookbook. You can find more details about it here.
And it looks like below on smaller screen, where we see a hamburger menu and on clicking on it, it goes down.
This completes part-3 of the series.
You can find the code for the same in this github repo.
