    w := 1900
    h := 1200
    divisor := gcd(w, h)
    aspect := fmt.Sprintf("%d:%d", w/divisor, h/divisor)

    func gcd(x, y int64) int64 {
        for y != 0 {
            x, y = y, x%y
        }
        return x
    }

What’s the use case for the CSS code? The `padding-top` value doesn’t account for the OS and browser’s chrome (status bar, URL bar, etc.), so the `.inner` element doesn’t fit into the viewport.

Not sure why make a whole website of this w := 1900 h := 1200 divisor := gcd(w, h) aspect := fmt.Sprintf("%d:%d", w/divisor, h/divisor) func gcd(x, y int64) int64 { for y != 0 { x, y = y, x%y } return x }

The site has a bit of Webkit-only CSS. Tip: don't use bleeding edge CSS like appearance , and if you do, at least test it in Chrome, Edge, and Firefox. You can fix the broken CSS for Firefox by adding -moz-appearance in addition to -webkit-appearance . https://developer.mozilla.org/en-US/docs/Web/CSS/-moz-appear...
