Thanks. As you can see in this screenshot, I removed the margin: https://www.loom.com/i/859ffe15ca7140e6b39f837d9f9d6bb7
On a 19″screen it looks like this: https://www.loom.com/i/4b6b3835092c4e91a6038712ea1b9118
And this screenshot is on a 23″screen: https://www.loom.com/i/fd85bc65f05642169b8037ca454bb131
It looks like I’m still doing something wrong…
