The Pattern
Every blog post on Light School has two links at the bottom: one to the previous post and one to the next. This is standard for blogs. What is less standard is what happens at the edges.
The first post links back to the last. The last post links forward to the first. There is no dead end. A reader who clicks "next" repeatedly will eventually loop back to where they started.
Why Circular
Most blogs treat the first post as a wall. You hit the beginning and there is nowhere to go except back. That felt wrong to me. If someone is reading through the archive and enjoying the posts, why stop them?
Circular navigation means there is always something to read next. It removes the moment where a reader has to decide what to do. Instead of a dead end, they get another post. Maybe they will read it. Maybe they will not. But the option is always there.
How I Build It
Each post has a navigation section at the bottom with two links. I set the previous and next targets based on the order posts appear on the blog index page. The first post in the list gets the last post as its "previous" link. The last post gets the first as its "next" link.
When I add a new post, I update the navigation in three places: the new post itself, the post that used to be first (or last, depending on where the new one goes), and the adjacent post. It is a small amount of manual work, but it keeps the loop intact.
A Small Detail That Matters
Navigation seems like a minor thing. It is just two links. But those two links shape how people experience the blog. A dead end says "you are done." A loop says "there is more if you want it."
I like building features that respect the reader's time without cutting them off. Circular navigation does that. It is quiet and simple, and most people will never notice it is circular at all. They will just notice that there is always another post to read.
The Loop
There is something satisfying about a system with no edges. Posts flow into each other endlessly, like a playlist on repeat. The blog is not a timeline with a beginning and an end. It is a circle. Start anywhere, read in any direction, and you will see everything eventually.
