So, i have this code and I can’t get this freaking thing to work. You can get the code here:

fiddle me baby

the part of the CSS dedicated to the images and text it’s in the end of the CSS, starts with:

/*new timeline*/
:root {
    scroll-behavior: smooth;
}

What I want is to get everything centered on page and adapting to the size of the window (including all devices). Can you shed some light on this, please?
