Fixing Elements - Some are overlapping my Images

[NiccosMedia]

Hi all other elements overlap my images on the mobile version, the green bar overlaps my swiper depending on the PX number of the device - how do I set a height so that the swiper is responsive? So that the elements underneath adjust? https://gctzhe88r4vjs3jj-63029412055.shopifypreview.com
