Mobile devices

To fully support mobile devices' capabilities, it is necessary the Seating Plan to have fixed position on touch devices. For this purpose the Seating Plan on mobile devices automaticaly gets class .ltd-seatplan--mobile which sets the position property on the element to fixed value. You can safely adjust it's rules to fit your needs as described in the example:

<style> {
        top: 6rem;

Keep in mind, that the page layout should be adjusted to cooperate with Seating Plan's fixed positioning on mobile devices.
