How to position custom shapes responsive to a quick stack Element

Hey, on the site Y esports Sevices i try to create a custom Design for my client.

I have designed an orange triangle that I want to place behind a black box (Div Block or Quick Stack Block) in the corner.

Desktop looks very good. The problem is responsive. For example, if I am in tablet view, I can position it correctly with “Position relative”. If I then change the canva width, the tag elements and jump down and the quick stack box gets more height. But the orange triangle stays in the same place. But it should move automatically in height with the Quick Box.

How can I solve this problem?
