WordPress automatically creates a category page every time it is called, with the newest post on top in backward date order. Remember that we added a plugin early on called "Sticky Post." We sometimes want one post to stay on top to provide information to our visitors that will help them to navigate better. So, in this image, the top post about shopping is a sticky post, and will always be on top. All the rest will be placed below it, with the newest on top.
I did an inset of a piece of the post writing screen to show you how it's done. At the very bottom of the page where we create a post, you'll find this box if you've activated the sticky post plugin. Just select "Sticky" and the post will stay on top. You'll see why we want to do this in some cases in the next step. Here's the real Shopping Category Page.
