    // the centering at desktop widths. (By default it uses auto-margins for
    // centering, but that's not reliable once left != 0.)

    // Override the default (100px) gap between top of viewport and top of
    // modal, bc we want it to be 0 on mobile. (This isn't the "real" top
    // property, it's just a hint to the reveal-modal js.)

    // On mobile, the modal's width is 100vw and we don't need to center
    // On tablet+, the modal's width is 80%, so 10% margin on each side:
    @media #{$medium-up} {
        margin: 4vh 10% 0; // Restore a gap at the top, too.
